Crash in mozilla::gfx::Source
Surface Volatile Data::Map
This bug was filed from the Socorro interface and is report bp-1f2bfa88-2029-49f5-bd43-4b3fe0170916. ============================================================= There are 41 in nightly 57 with buildid 20170916100147 and 73 for FennecAndroid with buildid 20170916100141. In analyzing the backtrace, the regression may have been introduced by patch  to fix bug 1380649.  https://hg.mozilla.org/mozilla-central/rev?node=722569a89186be92efbaebfa99005e5c46e27cf5
The signature is ranked #4 in nightly top-crashers for FennecAndroid.
I was expecting the diagnostic assert to crash (to figure out what went wrong) but not nearly as often as we are seeing (it was relatively rarely observed, or so I thought...). Backed out the offending change and I think the traces I've looked at gave me the information I needed to solve the original problem.
I'm apparently experiencing this crash pretty regularly on macOS 10.12.6 today, so if you need any additional info or testing let me know.
FWIW, this also ended up being a top crash on OSX, with a staggering 90% of all OSX crashes.

Really, given 3 reports over 2 years of images occasionally missing off pages in Firefox, I did not expect it to be happening constantly to every nightly user :(. This has not been a good weekend for me and crashes it seems.
