So I revisited the bisection with Eric. It seems that the initial reproduction case was actually reproducing a crash in the test. We have not been able to reproduce this crashing image diff issue that the bot is seeing. But we found that the crash is only happening on the release builds and started on r278417. a debug build of r278417 does not seem to crash. 

I am uncertain how a version bump in r278417 could have anything to do with this, but our archived builds seem to point to this revision as starting some kind of problem.
