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.

litemotiv wrote:Can you give more information about which ISO you installed, how you installed it, and which steps you have taken after finishing the installation procedure?
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

[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The fullrecall package is unmaintained, poorly written, and out of date (the latest version on the fullrecall website is 1.5.2).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 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.

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."

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

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

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.

Segmentation fault
Jack in running and it works fine with other applications. I'm using the package from extra that is the 2.5 version, I've compiled ardour 2.7 but i got the same error when running it.

I solved it, I think it's a bug in Ardour, but maybe could be also Arch related (someone wants to try it on other distros?), in fact to get Ardour starting you absolutely need the hostname "localhost" configured in /etc/hosts.
For example this is my currently working /etc/hosts
# /etc/hosts: static lookup table for host names
#<ip-address> <hostname.domain.org> <hostname>
#HOSTNAME (the same of rc.conf)
127.0.0.1 arch.localdomain arch
#ardour workaround
127.0.0.2 localhost.localdomain localhost

[Solved] pSX Segmentation Fault - [Partially Solved] pSX problems

Alright, I think that I've solved the segmentation fault thing that was happening in pSX whenever I ran it (I use Arch x86_64). I'm not sure what was wrong, but after installing lib32-intel-dri-7.11.2-2 via pacman pSX appeared to work fine. The only other problems I've encountered so far is that (1) installing one of the alsa plugin things (not sure which one since I was installing more than one at the time) seems to make it crash and stay crashed as long as the plugins are installed, (2) another problem was that when I try to load a savestate while running a loaded savestate of Final Fantasy 7 in pSX (I say FF7 because that's the only game I've tried playing so far) causes pSX to crash with a segmentation error, (3) and the last problem, which does happen to be the least important/crippling is that while pSX is running I keep getting a message displayed to xterm saying: "sound: underrun". That's pretty much it. So if any of you have been having trouble getting pSX to run on an x86_64 install of Arch/have been getting segmentation fault errors when you try to run pSX on Arch x86_64 just install lib32-intel-dri or the applicable alternative and it should hopefully work.

I ran into this same problem after an upgrade on a Thinkpad T60 and this did fix the problem.
Thanks to Roxas for posting the solution.

Labwindows/CVI OI crashes when running sequence on the deployed system

My Teststand Sequence runs fine on the development system. But when I run it on the target system using the Labwindows/CVI OI it sometimes just crashes and the Microsoft bugreporting tool comes up (see attached screenshot). If I run the OI out of the CVI development environment, it only shows a useless segmentation fault message when it crashes. Any ideas, how to find the reason for the crashes ?
Is there any option ( other than making screenshots) to save the information collected by Microsoft  and to use it for finding the bug ?

Hi Allen,
Yes it is a popup panel used for input of serial and part number in a customized preUUT callback.
But installing But installing CVI runtime 8.0 doesn't solve the problem.
It still sometimes crashes and sometimes the popup panel looks hosed (see attached pictures).  In that case running the sequence was OK and the during the next run of the preUUT callback the panel looked OK again. But when closing the OI ,there were error messages ( see attachment) .
It seems that there is some memory corruption going on, but where ? The code in the preUUT callback seems to run fine on the development system ( neither crash nor corrupted panel) and is also used in two other sequences running on other PCs without showing that problem so far.

Segmentation fault in SQL*Plus

Late yesterday afternoon, I tried to query a table in my
database and received a segmentation fault(core dumped). I
receive the segmentation fault only when trying to query 4
tables (out of a total of about 20) and only in SQL*Plus. If I
query from svrmgrl or through an ODBC connection, I have no
problems. I tried reinstallng SQL*Plus, but that did not help.
Any ideas?
Thanks

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 when using snapshot isolation with Berkeley DB 6.1.19 and 5.1.29

Hello,
I have been experimenting with snapshot isolation with Berkeley DB, but I find that it frequently triggers a segmentation fault when write transactions are in progress. The following test program reliably demonstrates the problem in Linux using either 5.1.29 or 6.1.19.
https://anl.app.box.com/s/3qq2yiij2676cg3vkgik
Compilation instructions are at the top of the file. The test program creates a temporary directory in /tmp, opens a new environment with the DB_MULTIVERSION flag, and spawns 8 threads. Each thread performs 100 transactional put operations using DB_TXN_SNAPSHOT. The stack trace when the program crashes generally looks like this:
Program received signal SIGSEGV, Segmentation fault.

I understand that this test program, with 8 concurrent (and deliberately conflicting) writers, is not an ideal use case for snapshot isolation, but this can be triggered in other scenarios as well.
You can disable snapshot isolation by toggling the value of the USE_SNAP #define near the top of the source, and the test program then runs fine without it.
Can someone help me to identify the problem?
many thanks,
-Phil

Hi Phil,
   We have taken a look at this in more detail and there was a bug in the code.   We have fixed the bug.     We will roll it into our next 6.1 release that we do.   If you would like an early patch that will go on top of 6.1.19, please email me at [email protected], reference this forum post and I can get a patch sent out to you.   It will be a .diff file that apply on the source code and then rebuild the library. Once again thanks for finding the issue, and providing a great test program which tremendously helped in getting this resolved.
thanks
mike

Segmentation Fault when connecting to SQL*Plus from Applications tier

Hi Everyone -
I am currently in the process of upgrading a client from 11.5.10.2 to 12.1.1 (eventually 12.1.3) on a OEL x86-64 server. I have laid down the software stack and followed all of the requirements as per the Installation manuals and 761566.1. I also have an open SR right now on this issue - but I wanted to see if any of you have ever run into the issue that I am encountering.
When I try to run adadmin/adpatch - I get to the prompt of providing the system user password and the utility simply exits. No errors in adpatch.log or adadmin.log (both are 0 bytes in size).
When I try to connect using SQL*Plus from the applications tier using either:
sqlplus apps/****@SID
sqlplus system/****@SID
I get a Segmentation Fault error. There are also no errors in my alert log file on the database tier. I found this error while attempting to apply the upgrade merge patch.
Has anyone ever seen s Segmentation Fault error? I have search MOS, found a couple of potential solutions - but nothing has solved the issue so far.
Thanks in advance...
Brenna

Are you on 11.1.0.5.0? Is this the database version?
No, my database tier is 11.2.0.3 (the database version displayed above was the client version running on the Application Tier.

"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.

Streamer gives segmentation fault when trying to grab a picture.

I'm testing streamer to grab output from my web camera.
Creating video works fine.
# streamer -q -c /dev/video0 -f rgb24 -r 3 -t 00:30:00 -o outfile.avi
But grabbing an image, gives segmentation fault.
# streamer -c /dev/video0 -b 16 -o outfile.jpeg
files / video: JPEG (JFIF) / audio: none
Segmentation fault
I got the commands from http://tldp.org/HOWTO/html_single/Webcam-HOWTO/#COMMAND
Am I doing something wrong?

Some extra information: If I run xawtv I get a blank screen but I can take a snapshot by pressing 'j' or by using the remote:
$ xawtv-remote snap jpeg full picture.jpeg
This actually gets an image from the camera. When I take a picture or close the xawtv client it briefly flashes an image of what the camera is seeing before returning back to black/closing.
I also get exactly the same error as on the link above.
