This bug was filed from the Socorro interface and is report bp-61018c40-8046-410f-9556-182422151214. ============================================================= STR: 1. Visit http://beta.unity3d.com/jonas/DT2/ 2. Once the levels load, click Play on the level on the left and after the level load finishes, Firefox will crash.
This looks like a very new regression. Current trunk suffers, but e.g. mozilla-central from 2015-12-06 is good (tested with mozregression).
Tried to run mozregression for this, but I noticed that the crash does not occur 100% of the runs, which led me to faulty bisect results. Currently the ftp is failing to serve me builds to try another bisection run. I take back comment 1 that 2015-12-06 would be good, believe it is actually bad but not 100% crashing. Mozilla-central from 2015-11-29 is now the earliest that I have seen this to crash with.

Bisecting again with multiple runs for confidence (seems to crash about 80% of the time in bad revisions) points to this as the offending commit: https://hg.mozilla.org/integration/mozilla-inbound/pushloghtml?fromchange=390cb35d92453aeccb0acf85dc113616f1006be1&tochange=7d1c223f397cdbcf494a4ef7ff7e56a5100b14c2 Jeff, could you take a peek to see if you can reproduce?
