             Summary: ast_pthread_mutex_lock calling ast_reentrancy_lock with lt=0x0
                 Key: ASTERISK-25948
                 URL: https://issues.asterisk.org/jira/browse/ASTERISK-25948
             Project: Asterisk
          Issue Type: Bug
      Security Level: None
          Components: General
    Affects Versions: 13.8.2, 11.22.0-rc1
            Reporter: Diederik de Groot
         Attachments: ast_25948.bt

defined(DETECT_DEADLOCKS)
defined(DEBUG_THREADS)

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)
