Segmentation fault running cdemocp under valgrind

I have problems with debugging multithreaded application with connection pooling under valgrind.
It faults at:

I have the same problem with other multithreaded applications that use OCI libraries.
Any suggestions ?
BTW. I also recieve tons of messages from valgrind about using uninitialized values.

Hi Paul,
I have the same problem with the J2SE 1.3.1_01 on an AMD Athlon 1 GHz processor with 128 MB RAM and with Linux kernel 2.4.0-4GB. Within the Forte For Java IDE, Xerces runs without any problems, but when I try to run it in a console (be it xterm, kvt or whatever), the segmentation fault occurs.
The solution appears to be typing "ulimit -s 2048" before running Xerces. Then it works in any console.
You can find the reason for this at http://www.apachelabs.org/tomcat-user/200109.mbox/%[email protected]%3E
Good luck!

Segmentation Fault running ifsJservctl

I just finished installing the 9iFS on a linux SUSE 7.2 box but I try to run the "ifsJservctl start" command, I am getting a segmentation fault. Just wondering if anybody else got this and if they manage to fix it.

The Analyzer depends heavily on low-level system details, which can vary among Linux distributions, and even among different releases of the same distribution. That is the reason why we support only a limited number of systems. Various components of Sun Studio, including the Analyzer, might run well on an unsupported system, run poorly, or simply crash.
Analyzer 7.6 is part of Sun Studio 12, released in 2008. The supported Linux systems for Studio 12 are rather old:
SuSE Linux Enterprise Server 9 with Service Pack 3
RedHat Enterprise Linux 4
More details are here: http://download.oracle.com/docs/cd/E19205-01/820-2063/
Oracle Solaris Studio 12.2, the current release, supports newer versions of Linux,
SuSE Linux Enterprise Server 11
RedHat Enterprise Linux 5
Oracle Enterprise Linux 5

[Solved] Get a segmentation fault message when try to run a Fullrecall

I'm running on Arch x86_64.
Then install this package with the packer.
https://aur.archlinux.org/packages/fullrecall/
run it with the terminal and get a segmentation fault message.
I have tried to install some lib32-* but still no luck.
http://sophie.zarb.org/distrib/Mageia/2 … 2f35d/deps
Any ideas ?
Otherwise, I will run it on Wine instead.

The fullrecall package is unmaintained, poorly written, and out of date (the latest version on the fullrecall website is 1.5.2). It's really hard to say why it is segfaulting but I would bet that it is because fullrecall is distributed as a binary rather than as source files. This means that it links against very specific versions of its dependencies, none of which are listed in the PKGBUILD. It's very possible that the versions in the arch repos of the various lib32-* dependencies that you installed are newer versions than the binary program requires.
You could try running namcap[1] on the built package and look for the specific version of the dependency you need in the Arch Rollback Machine[2], but I'm not sure how much that will help you. If you do manage to get it working, please adopt and update the package in the AUR.

Segmentation Fault given when running passwd

This is an entirely new setup.
Command run:
# passwd
Expected Result:
Would be able to change password of current user.
Actual Result:
Immediately outputs "Segmentation fault" to the console.
I'm entirely new to Arch linux, and somewhat new to linux in general (one year of ubuntu). I've googled around, and found that https://bugzilla.redhat.com/show_bug.cgi?id=590247 describes the same problem and that a solution is provided in comment 9. I read the man page for pacman, and decided that "# pacman -S "nss-softokn>=3.12"" would be the arch linux equivalent, but that didn't work. Please help me.

The filename of the ISO is "archlinux-2010.05-core-x86_64.iso". After 'finishing the installation procedure' (assuming that installation ends at the point that you can login as root at the console without the help of the disk), I fiddled around to make the wireless connection connect automatically, abandoned that finding out that it would be easier once I had a gui set up, installed KDE, found it wouldn't let me log in as root forever, added a user, and attempted to set a password for it.

Welcome to the boards.
A couple of things: you can always search for package details using the Packages link at the top of the page: nss-softokn isn't an Arch package - the package that contains passwd is shadow http://www.archlinux.org/packages/core/i686/shadow/
Make sure you have the correct version installed (4.1.4.2-3): pacman Syu && pacman -S shadow
For future reference, you downgrade like so: https://wiki.archlinux.org/index.php/Downgrade
This worked, thanks very much

"Segmentation fault" while running code, how can I increase the stack size?

Hi, I only have very limited knowledge about c+ codes and compiling them and I would be very happy if someone can assist me.
My problem: I have two c++ codes, one with an array size of ~100,000, the other with ~1,500,000. When I compile them using terminal g++ -o commands, the smaller one works with no problem (it takes less than a minute to run), the larger one gives "Segmentation fault". I think it is a memory allocation problem and I am not an expert on dynamic memory allocation which I want to avoid for now.
My question: When I compile the large code in Windows Visual Basic, I can go to settings to increase the stack and heap sizes and it does work. Is there a similar thing in OS X Leopard? I found some commands to do that in the terminal window but I wasn't able to resolve my problem.
Thanks for all your help.

Thanks for the link, I actually looked for a developer discussion group but was not able to find it through the main discussion page. I reposted to my question there.

Segmentation Fault in db- put() fun with BDB ver 4.5.20/4.6.19 in linux

I am working on porting an application that runs on sun solaris sparc (OS ver 5.8) with Berkeley DB ver 4.2.50 into suse linux [ Linux version 2.6.5-7.244-smp (gcc version 3.3.3 (SuSE Linux)) ]. I have compiled the application in linux and i am getting segmentation fault error while running the application. The error occurs while the objects are loaded from the database into berkeley cache. The application fails in db->put function while loading the objects. This segmentation fault error is not consistently occuring every time on the same object. Sometimes it throws the error while loading the first object itself or sometimes it throws after loading couple of objects. But the stack trace shows the same function whenever it crashes.
Given below is the stack trace of the application when it throws SIGSEGV.

We are using the Sybase Adaptive DB server running in Solaris/Linux servers. The same application that runs in Solaris connecting to Sybase DB (in solaris) is working perfectly fine. And the application that i am working in linux connects to the Sybase DB running in linux server.
Please let me know what could be the issue that is causing our application to segmentation fault.

RefServer.cpp:296Did you build the libraries stripped or otherwise remove debugging information?
run "file /opt/home/pesprm/local/db-4.6.19/db-4.6.19/build_unix/.libs/libdb-4.6.so"
Also, if I'm not mistaken this is Linux you're porting to, right? Might want to drop the "/opt" Solaris-ism as you continue to port more to Linux.
The code that calls the db->put() function is given
below:
     if (pTable->getDataOffset() == -1)Does this return an unsigned or signed value?
pTable->setDataOffset(
t( (int)(pObj->getDataBufferStartPos() -
pObj->getDataStartPos()) );You cast to int here, what's the background reasoning for it?
     DB* pdb = pTable->getDB();
     int rc = 0;You don't check pdb is valid.
Synchronize
e sync(pPrimaryKey->getKeyBufferCriticalSection());
pPrimaryKey->getKeyValues(pObj,
, pPrimaryKey->getKeyBuffer());
     DBT key, data;
     memset(&key, 0, sizeof(DBT));
     key.flags = DB_DBT_USERMEM;
key.data =
= (void*)pPrimaryKey->getKeyBuffer().getBuffer();Do you verify this is even valid? Have you also checked the code within a debugger and verified the logic is correct?
key.ulen = key.size =
= pPrimaryKey->getKeyBuffer().getBufferLength();Same thing.
     memset(&data, 0, sizeof(DBT));
     data.flags = DB_DBT_USERMEM;
     if (pTable->isPrimaryDb())
          data.data = (void*)pObj->getDataBufferStartPos();
          data.ulen = data.size = pObj->getDataBufferSize();How do we know these are even valid? You're coming from the perspective that your code makes no mistakes when I have a hunch it does.
rc = pdb->put(pdb, (DB_TXN*)transactionId, &key,
y, &data, DB_NOOVERWRITE);Right, and this will most definitely result in a segmentation violation if you don't pass it valid data.
You're on Linux, I highly suggest you download and build Valgrind, run your application w/ valgrind --tool=memcheck, and get back to us. Also, don't strip debugging information from the berkeley db libraries during this phase of troubleshooting - especially when you're still porting something over.
I have tried using the BDB versions
4.5.20/4.6.18/4.6.19 with the application and it
throws segmentation fault error with all versions of
BDB.Because the issue isn't within BDB.
We are using the Sybase Adaptive DB server running in
Solaris/Linux servers. The same application that
runs in Solaris connecting to Sybase DB (in solaris)
is working perfectly fine.More correctly, it was working perfectly fine under Solaris. That doesn't even mean that it's not taking part in undefined behavior - it just means it "worked."

Svrmgrl segmentation fault!

Hi everyone.
I installed Oracle 8.0.5.1 Enterprise Edition on a RedHat 6.0 box
with 2 Pentium III processors. The installation went smoothly but
when I ran the svrmgrl the familiar message "segmentation fault
(core dumped)" appears. The funny thing is that I have installed
the same product on a SuSE 6.1 with a Pentium II 233Mhz and it
runs OK.
Any suggestions?

GNU compiled app crashes with signal 11: Segmentation Fault

Hi Community,
I know this is not a GNU oriented forum, but maybe this is a common issue.
We have a C++ multi-threaded application running properly in Solaris 9 Sparc. Due to some issues mostly related to the NICs we needed to have the application running in Solaris 10 x86. The problem is that the compilation is ok (always with GNU) but during run time, we have the application crashing in different instructions because of a signal 11.
It always crashes in a malloc call within the libstdc++.so.6
It was compiled with the option -mt and -lthread. Is this a known problem? Do you recommend any direction to start seeking for a solution?
Pls, find attached the gdb outcomes after the crash.
Thanks in advance, Pablo

A crash in malloc in multi-threaded code could be a bug in the system malloc or a failure to use a thread-safe malloc. The default Solaris malloc in /usr/lib/libc.so.* is thread-safe.
A crash in malloc can also be caused by a heap corruption. Probably the most common causes of heap corruption are
- writing beyond the bounds of a buffer or variable (off by one, for example)
- deleting the same object more than once
- using an invalid pointer:
--- uninitialized
--- pointing to a deleted object
--- pointing to an out-of-scope object
- failure to guard a critical region
- failing to declare shared objects as volatile

Memory violation / segmentation fault at k3b, kdenlive and wine

Hello, i cant run k3b, kdenlive and wine.
When i try to run some of listed apliactions i got segmentation fault.
Here are some logs:

I launched Wine separated version installed by PlayOnLinux, and just made a bash script in /usr/bin/wine:
#!/bin/bash
/home/webnull/.PlayOnLinux/WineVersions/1.1.44/usr/bin/wine $@
And wine runs from /home/webnull/.PlayOnLinux/WineVersions/1.1.44/usr/bin/win using /usr/bin/wine but this is not a solution, its just a shortcut to other installed wine.

Here is some additional information that may or may not be of any relevance. I do not know.
On the old server, I compiled the code with the compilation commands: f95 program.for
I was able to compile and execute code with small, medium size or large arrays (with or without the additional -openmp flag).
If I repeat the same command: f95 program.for
on the new server, I get the following compilation error message for programs with medium size and large arrays:
In function `newmaxmalecor':
/mnt/ide0/home/gustaf/education/programming/cesprod100//chicago.for:4340: relocation truncated to fit: R_X86_64_32 against symbol
If I compile with the additional flags: f95 -xmodel=medium -m64 program.for
on the new server, there are no compilation errors and I can run the code in sequence.
However, when I compile with
f95 -xmodel=medim -m64 -openmp program.for
on the new server, compilation works, but I cannot execute the code with medium size and large arrays.
The programs for which I have to add the "-xmodel=medium" flag on the new server to be able to compile the code and run it in sequence, are exactly the ones for which I get segmentation faults when I introduce the openmp flag and try to execute the code in parallel fashion.
Is this just a coincidence?

Segmentation fault during index

Can anyone tell me where to start looking to find out why I'm getting a "Segmentation fault" error while trying to "addIndex" to a container via the dbxml command line? I'm getting this in my messages logs:
dbxml[8825]: segfault at ecd3000 ip 00957faa sp bfc65060 error 4 in libdbxml-2.4.so[80f000+278000]
OR
dbxml[8937]: segfault at 0 ip 00493fea sp bfd7e07c error 4 in libc-2.8.so[41d000+163000]
That's about all I know...
Any thoughts?
Thanks,
Kevin

Kevin,
You'll have to debug this. If you have a debug build you can run the dbxml shell under gdb.

Python segmentation fault with matplotlib and opencv2

Once again fellow archers, I am in need of your help.
I have a file, Test1.py, which uses cv2, pylab, and numpy.
Excluding either pylab or cv2 functions, I can make the rest of the script work, but when pylab is imported, calling cv2's imshow() function causes a "segmentation fault (core dumped)".
By the sound of it, I thought it might come from the underlying C stuff, rather than python.
So I ran it through gdb.
This is where I need help. I'm not sure how to interprete the backtrace, and I probably wouldn't know what to to if I were.
Perhaps a problem with glib or GObject?
Below are the python script in question (it a template for a school assignment), and the gdb trace.

Thank you so much!
This (ugly) workaround might have saved me from a lot of trouble with this semester's exercises.
Just to be clear, the solution is:
Import opencv
Call namedWindow
Do the rest of the imports
Do the rest of the script
Corect?
I'm hesitant to mark the thread as solved, as the problem is still very much there, this workaround just allows us to ignore it.

The programs for which I have to add the "-xmodel=medium" flag on the new server to be able to compile the code and run it in sequence, are exactly the ones for which I get segmentation faults when I introduce the openmp flag and try to execute the code in parallel fashion.
Is this just a coincidence?

Apache - Weblogic plug-in - Segmentation fault. Please Help me!

Hi all,
Im trying to set up Apache weblogic plug-in, and im having problems with
that.
Im running Solaris 9 with Apache/1.3.26 (Unix) and Weblogic 7 with sp2.
Here is what i did:
I copied mod_wl_ssl.so from
/bea/weblogic700/server/lib/solaris/mod_wl_ssl.so to /usr/apache/libexec
Added entries in httpd.conf as
LoadModule weblogic_module /usr/apache/libexec/mod_wl_ssl.so
AddModule mod_weblogic.c
<LocationMatch "\.jsp$">
SetHandler weblogic-handler

<IfModule mod_weblogic.c>
WebLogicHost 127.0.0.1
WebLogicPort 7001
HungServerRecoverSecs 300
ConnectTimeoutSecs 5
</IfModule>
When i access the url with out specifying port 7001 it's not working.
I checked the /var/apache/logs/error_log file. Im getting the error as
child pid 805 exit signal Segmentation Fault (11)
Am i missing anything here?
Thank you
Raja

You may want to check the certifications for Solaris 9 and the Apache plug-in at
http://e-docs.bea.com/wls/certifications/certifications/sun_solaris9.html#40366.
It looks like you will have to upgrade to at least Apache 2.0.39. We had to do
this on Solaris 8 as well.

Try with just that.
Another thing is that I am unsure as to whether we have tested

when
building apache? Did you use GCC?

That means that your apache instance is compiled with -DEAPI

Can you please try to set Debug ALL and get the log in

Are you using modssl or any apache with EAPI compiled in?
Otherwise, you should be using the mod_wl.so.
As well, please set Debug ALL to see if we can get more

as

Ssh has stopped working - reverse mapping causes segmentation fault

This was working on Friday, believe me. I haven't done anything that I'm aware of (apart from reboot the machine) to change things, except in trying to fix it.
Briefly, ssh crashes out with a segmentation fault and a crash log (below). Poking around with verbosity gives (real ip obscured):
% ssh ip4 -vvvv

Segmentation fault
I get similar reports for %ssh FQDN and %ssh $USER@[FQDN*|*ip4].
Although I'm trying to ssh to a machine on another continent, trying to ssh into my own machine (from a Terminal window on my own machine) also does not work. Setting UseDNS no in /etc/sshd_config on my machine does not help. Oddly, trying to ssh to my own machine by
%ssh 127.0.0.1 gives
debug1: Enabling compatibility mode for protocol 2.0
debug1: Local version string SSH-2.0-OpenSSH_3.8.1p1

and then works (after a lot more info).
I can ssh into this machine from elsewhere, I just can't ssh out. Below the crash log is a report from running a server with
% sudo sshd -D -ddd -e -p 10000
and connecting with
% ssh -vvv -p 10000 $USER@FQDN

10.4.7 fixed this.
But broke iCal. . .
Actually, I never had any problems with 10.4.6, but ssh on my nat'ed Intel Macbook now segfaults when doing reverse mapping after upgrading to 10.4.7.

Compiling Flex2 in Linux - Segmentation Fault

Dear all
I am a newbie in Flex and my system is now running Ubuntu
7.04. Java-6 and Java-5 are already installed.
I have download and unzip the flex2 sdk under
/usr/local/flex2.
But when I tried to build the sampes by running:
./build-samples.sh, it only show the following error and the flex
won't compile.
processing ./hybridstore/build.sh
Loading configuration file
/usr/local/flex2/frameworks/flex-config.xml
Segmentation fault (core dumped)
Can any body please help me out of these problem?
Thanks in advance.
