Weird, I haven't seen this assertion actually go off before. I'll move this to the GC component, because while the assertion runs during the cycle collector I think it indicates an issue with gray marking from the GC.

It looks like this assertion has happened before, in at least 2019: bug 1399866.

[Jon Coppeard (:jonco)]

This is almost certainly due to bug 1837620 which made some script -> shape edges weak. Weak black -> gray edges are OK themselves, but the "jit-masm-ptr" edge this is complaining about is not a weak edge. I think we are missing an expose call when creating a snapshot of the cache IR.

Tier 1 failure here.

[Jon Coppeard (:jonco)]

Attachment: Bug 1842584 - Expose the targets of weak references in cache IR stubs when creating snapshots r?jandem

Currently there's a read barrier in WarpScriptOracle::maybeInlineIC but this
only handles making things safe for incremental GC, it doesn't handle gray
unmarking.

This is necessary because while black -> gray weak edges are OK (the edge will be
cleared if the target dies), here we are taking the target of a weak edge and
making a strong edge to it. We need to expose to do gray unmarking at this
point otherwise we can create a strong black -> gray edge.
