Bugzilla Bug 13204

I have only tested this while 'talking' to an MS Netmeeting user. I am not sure
if this happens with other gnomemeeting 0.94.1 users, as I was unable to find
anyone to help me test this out.

gnomemeeting 0.94.1 segfaults after a few minutes of talking. We tried this at
least a dozen times, and there was not one session that was not ended by a
segfault after about 2 or 3 minutes.

See the attached strace log. It is bzip2 compressed, since I don't feel like
sending 1.3 MB over dial up.

I am looking for other gnomemeeting 0.94.1 users to test this out with.

Blah, forgot emerge info:

firs of all, try lowering your optimizations.

Okay, any suggestions on what to shave off?

make -O3 be -O2 instead.

Okay, I tried the following with the same person who is using Netmeeting from
before:

replaced -O3 with -O2 . Result: Segfaults 1min 30sec in , three times in a row
replaced -O2 with -O0 . Result: Segfaults 1min 30 sec in, three times in a row

I'm no developer, but that repeated time pattern is.. odd to say the least.

What would you like me to try next? I'm still curious if this will happen with
another gnomemeeting user. Perhaps we could try it if you have the time.

i dont have a webcam and stuff :/

Anyway, can you debugbuild it and give a backtrace (easiest way is to add
'inherit debug' at the top of the gnomemeeting ebuild) ?

Okay, so I add "inherit debug" at the top of the ebuild, and by backtrace do
you
mean an strace log? Appolgies for my lack of a clue, and thanks for the
patience.

No, when it crashes it comes up with a dialog like 'close this app or file a
bug
report'. Choose the file a bugreport one. The first dialog in bug-buddy
generates a backtrace (heap of debugger related output), we would like to see
that. And then cancel bug-byddy, dont file a bugreport trough it just yet.

gnomemeeting backtrace 1

how is this problem with the new gnomemeeting 0.96 ?

I hadn't noticed it was out, I will give it a shot when the other person comes
on line.

I'll try building it 'normally' at first.

closing, reopen if the problem still exists with 0.96
