Summary:ASTERISK-25948: ast_pthread_mutex_lock calling ast_reentrancy_lock with lt=0x0
Reporter:Diederik de Groot (dkdegroot)Labels:asterisk crash lock voicemail
Date Opened:2016-04-21 08:09:15Date Closed:2016-09-23 14:24:34
Versions:11.22.0-rc1 13.8.2 Frequency of
One Time
Environment:Attachments:( 0) ast_25948.txt

Error Steps:
- t->tracking = 0            (lock.c: 245)
- which causes lt = NULL      (lock.c:246)
- Which finally results in a  call to ast_reentrancy_lock(lt) (lock.c:289)  causing a segfault.

Potential Solutions:
- assert pointer != NULL in ast_reentrancy_lock
- include this current block with the previous if(lt)     (lock.c: 249)
