Steven can you take a look or assign someone to look into it?

Jon, is this is in the GC area?

One stack is missing but the other involves off-thread parsing and we don't collect off-thread parse zones so I don't think it's GC related. It could be the same issue as bug 1601286.

Since it involves off-thread parsing so it should go away when stencil lands.

Jon are you working on this?

(In reply to Andreea Pavel [:apavel] from comment #15)

Jon are you working on this?

No, this is a race with off-thread parsing that will disappear when Stencil lands. Until then I expect we can add a suppression.

This race involves off-thread parsing and will go away when Stenil lands.

https://hg.mozilla.org/mozilla-central/rev/a094bb764a5d

Has Stenil landed? Is there a tracking bug for that? Can we remove this suppression?

(Sorry for the random ping, trying to GC all the old gunk in the suppression list)

Has Stenil landed? Is there a tracking bug for that? Can we remove this suppression?
Parts of stencil have landed but the relevant bug here is bug 1662102.

Triage: the exact reported issue doesn't currently appear on CI BUT removing the suppression for this problem causes instances of Bug 1615608 to appear, presumably from multiple instances of this issue ramming into eachother.

Nothing to do, just checking all the older suppression!

Whoops, this wasn't supposed to be closed!

Enough of stencil-mvp is landed that currentNameHasEscapes should not use JSAtoms at all and the potential race should be gone. The comments in Bug 1615608 suggest that the tsan internal issues are gone too, so I wonder if we can remove suppression now?

Didn't reproduce this time, so looks like it is indeed fixed!
