Crash in mozilla::layers::APZEvent
State::Process APZState Change
This bug was filed from the Socorro interface and is report bp-8bb1e627-1793-4304-b0ee-150302160827. ============================================================= Seen while looking at nightly crash stats: http://bit.ly/2cioCUF. Crash affects Windows and Mac. Adding ni on kats to weigh in since it looks it touches code in an area he works in.
As of bug 1289650 mAPZEventState gets nulled out in the ChromeProcessController before the object is destroyed, so we need to add null checks. This crash looks like it happens because we invoke a function on a destroyed APZEventState object during shutdown. Assigning to Ryan; the patch should be pretty straightforward. Crash-stats is already showing 20 of these crashes so we should fix it soonish.
18 crashes on Mac in Nightly 20160826030226, making it the #2 Mac crash. (On Windows it's #36 in that Nightly, with 4 crashes so far.)
