Even after the fix in bug 930884, we are still seeing this crash happen in a child process on debug emulators.

This patch [1] on pine makes mochitest check for child process crashes after a test run, and it seems to happen every time. Opt emulators are fine, this seems to be debug only. This is blocking us from landing child process crash detection for future crashes.

Side note: opt emulators have a different graphics related shutdown crash (see bug 983489) which may or may not be related.

Seems crash at egl.cpp ln 303 nativeWindow->cancelBuffer(nativeWindow, buffer); Looks like cancelBuffer is not initialize properly. As it's random happen, still verify.

This is a new and unexpected feature request for 1.4. I need to escalate because it will change our 2.0 plans if these are all to be done.

The rationale for making this a blocker is because it blocks a blocker. Please decide how you plan to proceed with the issue.

Re-triage - this doesn't have proof of being a user facing crash on devices, it only happens in debug build situations & tests. So renoming to reevaluate.
blocking-b2g: 1.4+ → 1.4?
This problem seems to happens only on emulator. On actual device, there is not use case to shutdown Compositor.
It seems to be fixed by Bug 986836. The problem happens only on b2g ICS emulator.

Based on this and based on the lack of user-facing effects, I'm going to remove the nom and we can hopefully close it when we've determined that bug 986836 has fixed it.

Hi Vincent,
Is there any finding on this bug?
Flags: needinfo?(vichen)
Will check this after Bug 983489 is landed. Bug 983489 backout again.
Flags: needinfo?(vichen)
ahal,
Would you please check if the crash still happen or not?
Flags: needinfo?(ahalberstadt)
If it's still an issue, this try run should reproduce it:

Andrew, 
I remember this crash only happen on Cedar.
Flags: needinfo?(ahalberstadt)
I think that was just because reftests were oop on cedar. OOP reftests have landed on m-c too though, so that try run should have the change. For some reason it looks like debug emulator mochitests aren't scheduled on try though? I'll need to look into that.
Flags: needinfo?(ahalberstadt)
Hm, weird. They're definitely scheduled on try, but for some reason that syntax doesn't seem to work. Maybe I need to specify all mochitests? Here's a new try run to test that theory:
https://tbpl.mozilla.org/?tree=Try&rev=6eb1527753f5
Those reds are known intermittents. But there are two other shutdown crashes that have signatures other than this. I filed bug 1016538 and bug 1016540 respectively for them.

So to answer the question it seems this specific issue is no longer a problem, but there are still child process shutdown related crashes that are preventing me from landing bug 969146.
