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,

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.

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
