Comment 1

[Alexandru Michis [:malexandru]]

Kris, this seems to be caused by the changes in Bug 1559659, could you please look into it?

(In reply to Alexandru Michis [:malexandru] from comment #1)

Kris, this seems to be caused by the changes in Bug 1559659, could you please look into it?

According to the comment here in Bug 1559659, this likely is related to changes in mozilla::Atomic. Is there someone who may know more about this?

Comment 3

[Kris Wright :KrisWright]

Brian, do you know what may be causing this testfail? We added a mozilla::Atomic<bool> in Bug 1559659. Could that be causing an issue?

Brian, do you know what may be causing this testfail? We added a mozilla::Atomic<bool> in Bug 1559659. Could that be causing an issue?

Yeah, this is probably causing the problem --- mozilla::Atomic<> accesses are recorded by default, and recorded events are disallowed on JS helper threads. I'll verify this later today and post a patch.
