866781 - Camcorder crashes after recording finished

Status: VERIFIED WORKSFORME

(Firefox OS Graveyard :: General, defect)

Description

[Diego Wilson [:diego]]

The crash is 100% reproducible on inari. Probably related to the layer refactoring.

Backtrace stopped: previous frame identical to this frame (corrupt stack?)

Unfortunately this stack only tells us that abort() was called.

Maybe try breaking on abort and __abort to hopefully get a better stack?

Any particular reason why you think that this might be related to the layer refactoring?

Yeah, I know it's not that helpful :( This is what I get when gdb traps the exception.

IIRC it didn't happen before https://hg.mozilla.org/mozilla-central/rev/ee5ca214e87c

I imagine this is the same crash as in the bug 866521, but let's see.

Diego, if you grab a patch from bug 866521, is it any better?  There are additional patches that may need to be picked up, bug 864017 depends on some, so it may take a bit to untangle it all.

[Milan Sreckovic [:milan] (needinfo for best results)]

This is either a dupe of bug 866521 or bug 866952 or a combination of those, but either way, this works for me now on central, no other patches necessary.  Diego, if you can still get it to crash, please reopen.

Works!
