=============================================================
We have a bunch of Fennec crashes that just show up [@ libxul.so@0xea2fb6 ] in crash-stats. Running the crash mentioned above through a tool I wrote to trawl the entire stack in the minidump gives (with non-helpful entries removed):
0x511d0984: libxul.so!gfxAndroidPlatform::~gfxAndroidPlatform [gfxAndroidPlatform.cpp:95d1bb200f4e : 46 + 0x1]

So for this example, we're crashing during shutdown, apparently in the gfxAndroidPlatform destructor. The frame that's in mozalloc.h is just "operator delete". I suspect this means we've previously corrupted memory, and we're just crashing here by happenstance.
I need to grab a few more minidumps from this crash and see if the same stack shows up.
