Crashlog

I've seen a few different tests crashing in WebCore::InlineBox::InlineBoxBitfields::isHorizontal() const + 8

imported/w3c/web-platform-tests/html/semantics/embedded-content/media-elements/interfaces/TextTrack/activeCues.html is the test that I've seen in results most often, but it is not the test that is referenced in the crashlog.

Earliest crash I can see on the flakiness dashboard with the media-elements/interfaces/TextTrack/activeCues.html test is: 10/17/2016 4:02:01 PM ~r207428
Comment 5 Ryan Haddad 2016-10-20 09:42:37 PDT
This is happening very frequently on the bots. I am trying to find steps to reproduce, but any help narrowing down the cause would be appreciated.
Comment 6 Jonathan Bedard 2016-10-20 10:16:13 PDT
Doing some flakiness analysis, when imported/w3c/web-platform-tests/html/semantics/embedded-content/media-elements/interfaces/TextTrack/activeCues.html fails, the following test sequence is always run first (at least, in all 8 of 8 cases tested):

Comment 7 Jonathan Bedard 2016-10-20 10:26:38 PDT
Less conclusive results for media/track/media-element-enqueue-event-crash.html.  The shared failure sequence follows.  More examples of test failures would help narrow down this list.

Is this still happening?
Comment 9 Ryan Haddad 2016-10-24 18:16:21 PDT
(In reply to comment #8)
> Is this still happening?

Yes, but I haven't been able to reproduce the crash locally.
Comment 10 Ryan Haddad 2016-11-01 16:54:02 PDT
This is still occurring intermittently on the bots, but I can't get it to report on demand locally.
