Summary: Siptrace traced_user_avp causes segfault in libmysqlclient

Initial Comment:
When I set the traced_user_avp in the Siptrace module it causes a segfault in libmysqlclient.so. Everything works fine if I do not set the traced_user_avp.

If I enable the query buffer I also get some messages about not enough free memory.

Hello Ryan,

Checked the backtrace for the query buffering crash, and It was definitely
cause by the same bug in siptrace, which was fixed.
Thanks for helping in tracing the problem.

Regards,
Vlad

Tried trunk and the problem is fixed. Also seemed to fix the issue when
using it with the query buffer as well.

I attached backtraces with the query buffer as well, from svnrevision:
2:8311M, that was showing the crashing. Just in case.

Thanks

Hello Ryan,

This has been fixed in trunk and in the 1.7 branch.  Could you please
update and give it a try ?
Also, I see that OpenSIPS crashes also when using insert buffering. Is it
possible to get a backtrace for that as well ?

Regards,
Vlad

I was using the tarball release off of the main opensips site.

I also forgot that this is on Scientific Linux 6.1 (RHEL Clone) 32 bit
with mysql 5.1.52.

I will get a backtrac. Since this is a development box I will try the
latest trunk version as well.

Message:
Hi Ryan,

what is the SVN revision of your opensips ? also, when crashing (without
buffering), I see you get a core file - could you please extract and post
here the backtrace ?

Thanks and regards,
Bogdan
