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.
