We have a segfault. It's not the newest code, so I didn't opened a jira yet.
Date: Thu Jul 22 01:23:06 2010 -0500
I advised to upgrade but it's not going so fast, and I think I found
something so I ask before we do the upgarde
I saw there were commits in media bug remove code, but I'm not sure it
The codec is destroyed in switch_core_media_bug_remove_all although
switch_codec_ready said it's ready.
I found that it could be removed in bug_remove or bug_prune too.
In those functions the write lock is locked, but in remove_all it's
unlocked before the codec destroy.
So I think it somehow the bug remove and session hangup happend in the
same time (I'm not 100% sure it's possible)
and remove_all tried to destroy the codec that was already destroyed.
I think the rwunlock sould go after the codec destroy in remove_all.
Please check, and let me know if my theory make sense :)
