CentOS 5.2
OpenSIPS: latest from svn (about an hour ago)
PostgreSQL libs: 8.3.4 (built against the same)
DB in writeback mode

Causes OpenSIPS to crash every time within a few minutes of starting. I can reproduce the crash by repeatedly reregistering a hard or soft phone, making a call from a successfully registered device, or anything else that touches the database. Reference build and config is OpenSER 1.2, which does not have the problem.

The core dump is too large to attach so I've posted it here:

Hello Brent.

Is that backtrace taken with gdb? The syntax does not loke familiar.
In case it does not, could you take the backtrace with gdb?

Regards.

Sergio.

Message:
After fiddling with this some more, it appears that I can only reproduce
this consistently if fork=yes in opensips.cfg. If I don't daemonize
opensips (run it bare, rather than through the init script) and let all the
output go to the console, it no longer crashes.

Please let me know if there's any other useful information that I can
provide.
