Possibly sec-high, except we only saw this twice and don't have a lot to go on.

So I'm very confused by this. The read stack makes sense, but:
- The variable that's being written seems like a thread-local variable, so not sure how that can race.
- The write that's racing is not accessible on any of the logs I've seen:
Previous read of size 8 at 0x7b7000061068 by thread T21:
[failed to restore the stack]
Do you know how to make sense of this?

If one of the stacks is never showing up, it is very likely that this is an incomplete suppression.
:gankra, I remember you did some work around rayon/crossbeam, is this supposed to be suppressed somehow?

Comment 3 has the allocation being part of crossbeam_deque::deque::Worker$LT$T$GT$::resize
Which we supress with race:crossbeam_deque*::resize\n.
But presumably the suppression doesn't work if the signature is only part of the allocation. I'm guessing the crossbeam_deque stuff we're running afoul of is in the corrupt stack? It's possible the only reason we're only ever seeing this with a corrupt stack is precisely because only the corrupt stacks slip past our suppressions.
I'm not sure if it's a good idea to supress e.g. rayon_core::registry::in_worker to try to make up for it.
(It is of course possible that this is a real issue, but I doubt it.)

Probably shouldn't be sec-high given the above.
