Summary:                    Crash on pri_schedule_event - t200_expire
Description: 
I have had multiple crashes using libpri 1.4.7 (see
http://bugs.digium.com/view.php?id=14243).

I now upgraded to libpri 1.4.9 (same Asterisk 1.4.22) and the issue still
happens.  Compiled with DONT_OPTIMIZE, DEBUG_CHANNEL_LOCK, and
DEBUG_THREADS

Here is the latest crash from today:
Program terminated with signal 11, Segmentation fault.

So, for anyone else still with this problem, the recommended fix is in
libpri 1.4.10.2.  Please update to this, and report back.  If everyone else
finds that this version fixes the crash, I will close this bug.
