Environment:Attachments:( 0) ast_bt.txt
( 1) jstorm_bt.5994
Description:Also, Zap->H323 (chan_h323) completely crashed PC.
I returned back to 1.2.9.1, so only one bt available.
Looks like this issue related to jitterbuffer.

I have the same issue, what follows are the full details:

This is /trunk 35630, make valgrind with -DDETECT_DEADLOCKS -DDEBUG_THREADS
The segfault for me happend when a callback agent answeres an Agent/ call.

jstorm_bt.5994 is my back trace, you will notice that abstract_jb.c line 206
(my bt) and 212 (reporters bt) call ast_test_flag, ast_test_flag ASSUMES that
p is initialized.  So the question really is, is the problem here in abstract_jb.c or in includes/asterisk/utils.h

Also ast_jb_do_usecheck assumes that there is an initialized struct in the pointer for a jitterbuffer in that channel.

The changes I did that caused this bug were done in a bad way, so I'm just going to revert them.  I'll implement what I intended in a better way next week.
