            Bug ID: 240022
           Summary: sem_wait broken by r350481
           Product: Base System
           Version: CURRENT
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Many People
          Priority: ---
         Component: threads
          Assignee: threads@FreeBSD.org
          Reporter: andrew@tao11.riddles.org.uk
                CC: kib@FreeBSD.org, tmunro@FreeBSD.org

r350481 confuses _pthread_cancel_enter and _thr_cancel_enter, which take
different parameters (int vs. struct pthread *). The result is that sem_wai=
t,
which calls _pthread_cancel_enter(1), segfaults because it ends up in
_thr_cancel_enter(1).

This breaks postgresql (easily reproduced by running regression tests) thou=
gh
it ought to be easily testable otherwise. (Originally reported to me by tmu=
nro)

Affects current and 12-stable.
