>          Issue Type: Bug
>      Security Level: None
>          Components: General
>    Affects Versions: 11.22.0-rc1, 13.8.2

> 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)
