Comment 1

[Ryan VanderMeulen [:RyanVM]]

Gabriele, this is permafailing when I attempt to run gtests under TSAN. Any thoughts on what might be going on here?

Comment 2

[Gabriele Svelto [:gsvelto]]

Is this a recent change? We've landed bug 1752703 recently which might change how the stack looks like and thus break the test. I'll check locally to see if that's indeed the case.

Comment 3

[Gabriele Svelto [:gsvelto]]

This doesn't seem to be related to bug 1752703, I don't know what's the issue here.

Comment 4

[Ryan VanderMeulen [:RyanVM]]

glandium, do you have any ideas what's breaking here? I'm hesitant to skip the test in TSAN without some idea of what's going on.

Comment 7

[Mike Hommey [:glandium]]

Can you do a new push, and paste the log here (because try logs expire quite quickly)?

Comment 8

[Mike Hommey [:glandium]]

Interestingly enough, the log in bug 1805820 works and has the info for this one.

Comment 9

[Mike Hommey [:glandium]]

So it looks like TSAN is preventing tail call optimization, and that breaks the test's assumptions. Presumably, adding a MOZ_TSAN_BLACKLIST on IntermediateCallback and/or LeafCallback would work around the problem.

[Christian Holler (:decoder)]

Fwiw, I'd be fine with disabling this test under TSan. Feel free to r? me on such a change.

Comment 12

[Ryan VanderMeulen [:RyanVM]]

I tried adding the MOZ_TSAN_BLACKLIST annotation to both IntermediateCallback and LeafCallback but the same failures are persisting. Given that, I'll just proceed with disabling the test per comment 11.
