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.

" getline(cin,stream) " gives segmentation fault error

Hi
In our application, we have a client and a server. Client and server communicate from network with inetd services. server listens the port with fd_set and get the the string with " select " as a command line argument. everything looks fine in communication but when the client sent a string over the network and server tries the read with getline(cin,stream ), application throws a segmentation fault error.
Code:
struct timeval t;
t.tv_sec=60;
t.tv_usec=0;
fd_set rset;
FD_ZERO(&rset);
FD_SET(STDIN_FILENO, &rset);
if(select(2, &rset,NULL,NULL,&t) == 0)
return NULL;
getline(cin, stream); *//application crashes here*
How can we solve this error ?
thanks for your kindly answers.

Thanks for your addressing Andrew. i have already tried it. nothing have changed. well, i have read SunStudio11_Cpp_UserGuide and applied what it says. i think, my error is not related with standart compiler. this caused by 3rdparty tools. i am working on them right now.It's quite possible that your 3rd party tools are causing your problem, but given the dependencies between the C++ run-time libraries and the thread library, the link statement you provided earlier still has problems:
/sunpro/11/bin/CC -xildoff /dev_obj/users/src/project/sample.o -L/dev_obj/users/src/lib -lcommonCode -L/3rdparty/sybase/ebf10536/lib -lblk_r -lct_r -lcs_r -lcomn_r -ltcl_r -lintl_r -L/usr/lib -lCstd -lnsl -ldl -lthread -lposix4 -lintl -lresolv -lsocket -lc -lcrypt -L/usr/perl5/5.00503/sun4-solaris/CORE -lperl /usr/perl5/5.00503/sun4-solaris/auto/DynaLoader/DynaLoader.a -L/3rdparty/roguewave/SUNPRO60/12s/lib -lctl12s8 -ldbt12s8 -ltls12s8 -L/3rdparty/roguewave/SUNPRO60/12s/lib -lstd12s8 -o /dev_obj/users/src/project/sampleYou should remove "-L/usr/lib -lCstd" from your link step, and probably "-lc" also.
Also, your compile steps include the "-staticlib=libC" option, but your link step does not. That may or may not cause problems. You can try adding it to your link step, but try that after removing the extra library options, because that option probably does nothing when supplied to a compile-only step.
Finally, what patch level are patches 108434 and 108434 at? The latest versions of those patches are 108434-24 and 108435-24:
http://developers.sun.com/sunstudio/downloads/patches/ss11_patches.html
In my experience, the patch levels have a huge impact on C++ run-time issues. Note that there are dramatic dependencies on the levels of those patches. Do not compile on a machine at 108434-24 and try running on a machine at 108434-14, for example. All your machines pretty much must be at the same patch level for these series of patches.
If none of that works, and you can't isolate the problem to your third-party tools, you can try using the newer thread library, located in /usr/lib/lwp and /usr/lib/lwp/64, IIRC (I don't have access to a Solaris 8 box right now to check). You can add "-R/usr/lib/lwp" to your link statement and pick up the newer thread model.
You should also explore upgrading Solaris. Solaris 8 is pretty much no longer supported and as you're finding out, there are some rather intricate dependencies under Solaris 8 that Sun really did a good job removing in Solaris 9 and especially Solaris 10.

PCManFM Segmentation fault when trying to open two windows

Hi
It seems to be a bug, but I don't know if it's Arch, or upstream related, so first of all I will post here.
What happens: When trying to open two different windows of the file manager PCManFM, it crashes systematically.
How to reproduce: Open an terminal, type "pcmanfm"; pcmanfm is now open. Open another terminal, or another tab, type "pcmanfm"; pcmanfm is now closed. Go back to the first term, and you'll see "Segmentation fault"

ozar wrote:While PCManFM is broken and rather annoying, note that you can open new tabs and windows from within the PCManFM window that already have open.
Yep, I'm using this function since I noticed that bug but it'll be cool if this problem could be fixed in the near future ^^

Segmentation fault when calling dbms_alert.register() procedure from OCCI

I am trying to call the dbms_alert.register() from the OCCI but I get segmentation fault when I run the program, here is the code snippet. I am gettin segmentation fault immediately after calling setSQL() method.
Environment *occiEnvironment_;
Connection *occiConnection_ ;
string userName("SCOTT");
string userPasswd("tiger");
string url("");
occiEnvironment_ = Environment::createEnvironment();
try{
occiConnection_ = occiEnvironment_->createConnection(userName,userPasswd,url);
Statement *occiStatement1;
cout << "Before setSQL" << endl;
occiStatement1->setSQL("BEGIN dbms_alert.register(:1); END;");
cout << "After setSQL" << endl;
string alert1("MY_ALERT");
occiStatement1->setString(1,alert1);
occiStatement1->execute();
catch (SQLException ea)
cout << ea.what();
}

Thanks for the reply, now I dont see segmentation fault.
I tried to exted the code further to wait for the registered events, I added the following code, I do get and event but then get the exception:
Statement *occiStatement1 = occiConnection_->createStatement();
Statement *occiStatement2 = occiConnection_->createStatement();
string alert, msg;
int status;
occiStatement1->setSQL("BEGIN dbms_alert.register(:1); END;");
string alert1("MY_ALERT");
occiStatement1->setString(1,alert1);
occiStatement1->execute();
occiStatement2->setSQL("BEGIN dbms_alert.waitany(:alert,:msg,:status); END;");
occiStatement2->registerOutParam(1, OCCICHAR, sizeof(alert));
occiStatement2->registerOutParam(2, OCCICHAR, sizeof(msg));
occiStatement2->registerOutParam(3, OCCIINT, sizeof(int));

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

One of the challenges in supporting Linux is the frequent changing of what ought to be stable public interfaces. We have found a number of changes in Red Hat 6 that affect the behavior of the compiler and applications built with the compiler.
We plan to support RH 6 (and Oracle Linux 6) in a future release of Studio.

Collect causes segmentation fault when profiling L2 data cache misses on T1

I am attempting to profile L2 data cache misses on a SUN T1000 server, but collect causes a segmentation fault when I choose to profile L2 data cache misses.
Is it possible to profile L2 data misses on the T1 processor?
Thanks!
-John
A simple hello world application and the failed profiling:
%] collect -p +on -h ecdm hello
Segmentation fault
I compiled with
CC -xhwcprof -xdebugformat=dwarf -g -03 -o hello hello.c

No it is not possible to profile L2 cache misses -- the chip does not generate
interrupts on performance register 0 (only register 1, which is hard-wired
to instruction count).
That said, we should not generate a segmentation fault. Exactly
which version of collect are you using? We did patch Studio 11
to correctly handle the US-T1, and Studio 12 express also
correctly handles it.
Is the SEGV on the collect command, or on the target it launches?

What version of iPhoto are you using and from where (and how) are you trying to import the photos?
As a first fix attempt try this: launch iPhoto with the Option key held down and create a new, test library. Import some photos and see if you get the same message. If you don't then the problem lies with your current library.

Hmm, that was my best shot.
1) Do you have all of the latest updates applied?
2) Did you try all of the work-arounds listed in the comments. Granted some of them are definite hacks
3) Just to cover all the bases, do you get the same result with both ImageResize() and ImageScaleToFit()?
If all else fails, you could always go the java route and try some java code to do the resize. Obviously not the ideal, but it is worth a shot. IIRC there is a thread around here somewhere with the cf/java code. But that was from before the switch in forums and I will be darned if I can find it right now!
Update: I will play around the sample image you posted tomorrow. Just to see if I can come up with anything.

Segmentation fault when enabling replication with SQL API

Hi,
I've compiled BDB 5.3.21 on Ubuntu 11.04 (x86) with the following configure options:
../dist/configure enable-sql enable-sql_compat enable-debug enable-tcl --with-tcl=/usr/lib
I was able to follow the Replication Usage Examples given in "Getting Started with the SQL APIs" to set up a set of replicated master/client databases.
However, after I exited out of the dbsql session that started replication on the master database and re-opened the master database with dbsql, executing "pragma replication_initial_master=ON;" followed by "pragma replication=ON;" led to a segmentation fault. gdb showed that the segmentation fault occurred at:
dbsql> pragma replication=ON;
Program received signal SIGSEGV, Segmentation fault.
0x0032d42b in __env_ref_get (dbenv=0x8056ad8, countp=0xbfffd498)

772          renv = infop->primary;
(gdb) list
767          REGENV *renv;
768          REGINFO *infop;
769
770          env = dbenv->env;
771          infop = env->reginfo;
772          renv = infop->primary;
773          *countp = renv->refcnt;
774          return (0);
775     }
776
(gdb)
Does anybody know of a solution to this or could this be a bug? Thanks in advance.
P.S. here's a stack trace:

Thank you for reporting this. I have been able to reproduce this crash in-house.
You need to specify the replication_initial_master and replication pragmas as part of initially creating your SQL database. The replication_initial_master pragma is not used or needed after the initial database creation at the initial master site. The replication=on pragma is a persistent setting that we remember internally the first time you specify it. This means that after specifying replication=on for the first time on a site, we will automatically restart replication for you in future dbsql sessions when we open the underlying Berkeley DB environment.
This gives you a very simple workaround: don't respecify replication=on when you reenter dbsql.
Of course, we shouldn't be crashing on an unnecessary pragma. I have added this to our list of fixes to consider for the future.
Thanks,

Segmentation fault when calling gpctr function from matlab mex file

I am trying to write a simple mex file for square wave generation using counter1 of PCI-6035E. I am using matlab's native compiler to compile and link with the nidaq32 library, ver.6.9.3, with no errors. When the mex function is called from a matlab script, however, the program crashes at the first call, to reset the counter. (I can generate a square wave with the test panel.)

Sorry for the delay in responding. I got caught up in other stuff. I am attaching my little program as requested. As you can see, I have just wrapped a mexFunction call round the example code for square wave generation. After I posted this, I tracked down a copy of BorlandC++, installed it on my computer and recompiled using that compiler and *b.* libraries. And would you know it, the program works. The question remains, though, why it doesn't work with Matlab's native lcc compiler. Plus, I have limited disk space, so if I can do without BorlandC, I can use the extra room. The runtime error was a Segmentation fault that I traced to the first call to GPCTR_Control.

Nodejs segmentation fault when using npm

I am using nodejs-0.8.14-1 and v8-3.14.0-1 on Raspberry Pi when I try to npm install a package I get a seg fault
[root@alarmpi ~]# npm install express
npm http GET https://registry.npmjs.org/express
npm http 304 https://registry.npmjs.org/express
Segmentation fault
I see this thread: https://bbs.archlinux.org/viewtopic.php?id=151400
That claims the problem is solved but it does not appear to be fixed for me. Any idea on what I can do to get this working?
Edit: If I keep on trying (npm install express) like 7 or 8 times it will finally install.

This seems to have cleared itself up over the long weekend. So I guess this is solved, not sure what is wrong or what fixed it though.

./iasdeploy ? gives Segmentation fault

We are running a Solaris 8, iplanet 6.5 and when testing the command iasdeploy we receive a very strange error message. Does this fault derive from running the deploy command while the webserver is running?
Also, we did not shut down the KJS and KXS before deploying an ear file, is it necessary?

I get the same, and I have tried this on two different computers. Did you get anywhere with the problem?
