=============================================================

Possible regression range based on Build ID: https://hg.mozilla.org/mozilla-central/pushloghtml?fromchange=5b33b070378ae0806bed0b5e5e34de429a29e7db&tochange=3f6b9aaed8cd57954e0c960cde06d25228196456

=============================================================
This crash stack doesn't make much sense. Frames 2-9 seem fine, but I don't see how MakeCurrent would call into ~AsyncPanZoomAnimation or nsTArray. I suspect those frames are bogus or got mis-symbolicated or something. From the regression range bug 1390386 looks like the most likely culprit - jgilbert, could you take a look?
