Bonus fun: this is going to be permaorange on Linux32 when we merge to beta. [Tracking Requested - why for this release]: merge bustage, closed tree, delayed b1.

marking as blocker for 55 as this would cause breakage on merge day

This is pretty darn frequent in general right now.

Any idea what could be going on here, Jon?

I can't see anything in the pushlog. Jan do you know of any JIT changes that might have caused this?

Bug 1311425 could have changed GC timing and exposed something I suppose.
So, if I parse correctly the stack, this crash is not (immediately) caused by one of the uses of finalization in OS.File code, but rather during worker shutdown. Looking at the code (which I haven't touched in ~5 years, so please bear with my poor memory), the most exotic thing that the worker allocates is a js-ctypes `statvfs` struct. Could it be possible that the recent patches have somehow affected js-ctypes struct finalization? There also used to be a hack when sending strings across workers, but I believe that it was removed ages ago.

(In reply to David Teller [:Yoric] (please use "needinfo") from comment #14) > Could it be possible that the > recent patches have somehow affected js-ctypes struct finalization? Bug 1352430 does affect object finalization but landed a month before this crash started showing up. Still could be related of course.
FYI, this is currently marked as blocking Monday's merge of 55 to Beta.
These crashes happen either when finalising JSScripts or when freeing LIFO allocations made by the baseline compiler. They happen during GC on a worker thread while the main thread is waiting for workers to shut down. I haven't been able to reproduce this or work out what's going wrong.

Based on my chat with RyanVM, this is not a blocker for 55.0b1 anymore. Untagging as such.

this looks to be fixed as of June 6th (2 instances on mozilla-beta on the 13th though). I would prefer to close this bug, but I don't know why this magically disappeared.

I've no idea what caused this or why it (mostly) disappeared again :(

At however many different bugs we're up to now, I'm bored with filing new ones for every random signature.

I'll just remove this test and the getAvailableFreeSpace function, as it doesn't seem to be used, and this code is not really maintained.

This appears to be the first test in the directory, so hopefully there's not some broader problem here. I'll do a bunch of retriggers for whatever subtest runs this directory to see if anything else shows up. https://treeherder.mozilla.org/#/jobs?repo=try&revision=6641445ef9925df33c3f4f896e257eb720b4d2d2

Hrmph. Something on the autoland branch must be breaking this, as I rebased to tip m-c. I guess I'll wait for the next merge and try again.
FWIW, it was bug 1379256 that caused merge conflicts.

I'm thinking it'd be lower risk to just skip the test on Beta rather than backporting the removal patch. What are your thoughts, mccr8?
