Applied the commits mentioned, acquire lock still succeeds in all cases, resulting in double lock behaviour, although my logging from GHC's RTS doesn't seem to indicate an out-of-order condition, which is weirder still. Probably need to move the logging into pthread_mutex itself...

I thought of something tonight: ghc also has condition variables, which will temporarily unlock mutexes without going through the "release" log. Are they in use here? Just to make sure we're looking at a complete log of what's happening

Fix merged in hrev57076.
Note:
See TracTickets
for help on using tickets.
There was some incorrect error checking on GHC side which has been fixed in this change: https://gitlab.haskell.org/ghc/ghc/-/merge_requests/6231/diffs
This can potentially result in OS_ACQUIRE_LOCK thinking the lock is held by the thread, when in fact it isn't.
From our IRC discussions I think your test is made with a version before this change.
I think it would be a good idea to check if that changes the behavior, before digging deeper into the Haiku side of things?
A few other notes about this from the IRC discussion:
The involved code is: https://gist.github.com/jessicah/49ce38312ea20462165233a876f12e17
In the logs, the "owner" is not the current mutex owner, but it is the thread emitting the log (this makes a difference in "begin ACQUIRE_LOCK", where we don't know who the previous owner is, and in "end ACQUIRE_LOCK" and "RELEASE LOCK" if the lock acquisition failed cleanly (in that case the "owner" field in the mutex would be -1 or point to the thread previously owning the lock).
