Interesting that we're seeing this on b2g18 too. Rob, your patches for bug 876426 and bug 876380 came up as possibly suspicious yesterday when looking at the regression range. Any chance you can take a look?

We see this frequently on b2g18 and it also affects Linux32 and Linux64 there.

It looks like we crash here: mTimer = do_CreateInstance("@mozilla.org/timer;1"); mTimer->InitWithFuncCallback(TimerCallback, this, timeout, nsITimer::TYPE_ONE_SHOT); on the call to InitFuncWithCallback, with mTimer null. How can this be null? I can only assume out of memory? But that doesn't make sense, this isn't a particularly large allocation and we should be crashing all over the place if mochitest-1 is low on memory.

Is this the same bug or related to what Aaron identified in https://bugzilla.mozilla.org/show_bug.cgi?id=744836#c32 ? Sounds awfully similar.
do_CreateInstance fails after xpcom-shutdown
Or perhaps after http://mxr.mozilla.org/mozilla-central/source/xpcom/build/nsXPComInit.cpp#597 Anyhow, after certain point during shutdown creating timers fail. We have null checks elsewhere for that.

Andrea/Ehsan patched this with a null check in bug 877638.
Depends on: 877638
