Leif Hedstrom updated TS-4598:
------------------------------
Description:
{code}
** 1237320 Dereference before null check **
___________________________________________
660 event_notice = (TSMgmtEvent *)arg;
deref_ptr: Directly dereferencing pointer event_notice.
661 index = (int)event_notice->id;
662 LLQ *func_q; // list of callback functions need to call
663
664 func_q = create_queue();
665 if (!func_q) {
CID 1237320 (#1 of 1): Dereference before null check (REVERSE_INULL)
check_after_deref: Null-checking event_notice suggests that it may be null, but it has already been dereferenced on all paths leading to the check.
666 if (event_notice)
667 TSEventDestroy(event_notice);
668 return NULL;
669 }
