[OpenSIPS-Users] segfault during msg_callback_process in opensip trunk r7406

[Bobby Smith]

While running a load test over the weekend, we ran into a segfault several
times that looks like it was happening around the same area.  This is in
revision 7406.

It doesn't really feel there's anything meaningful or useful in the core
dump, but perhaps looking at the code path could help.  We reverted back to
branch 1.6 from svn and avoided the crash for 72 hours straight, while
before it was crashing about every few hours.

See below, and thanks.
