Any ideas?

MOZ_RELEASE_ASSERT(aFailureHandling == DontAssertDispatchSuccess || ((bool)(!!(!NS_FAILED_impl(rv)))))

It means someone tried to dispatch tasks to a task queue that had been shut down.

mozilla::detail::RunnableMethodImpl<mozilla::net::CacheFileIOManager* const, nsresult ( mozilla::net::CacheFileIOManager::*)(void), 1, 0>::Run()

I think that "someone" is CacheFileIOManager.

[Michal Novotny [:michal]]

I don't think it is CacheFileIOManager. We don't use task queues at all in netwerk code. Looks like a wrong stack.

[Abe - QA (:Abe_LV)]

It seems Audio/Video: Playback related.

Comment 5

[Jean-Yves Avenard [:jya]]

JW, how can you check with the windows stack trace the name of the taskqueue ? (ref bug 1359309)

Comment 6

[JW Wang [:jwwang] [:jw_wang]]

No. I expect it to show up in the "MOZ_CRASH Reason" field.

Mass change P1->P2 to align with new Mozilla triage process

Moving to p3 because no activity for at least 1 year(s).

Since the crash volume is low (less than 5 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.

Closing because no crashes reported for 12 weeks.
