Hard to believe this isn't related to one of the other eleventy billion B2G b2ginstance.py crashes, but the stack was different enough from the others on file that I decided it might as well have its own bug. https://tbpl.mozilla.org/php/getParsedLog.php?id=41377797&tree=Mozilla-Inbound b2g_emulator_vm mozilla-inbound opt test crashtest-2 on 2014-06-09 12:58:42 PDT for push 687e8799e88f slave: tst-linux64-spot-984 13:04:24 INFO -

Waldo's push right before comment 0 is looking very suspicious to me. https://tbpl.mozilla.org/?tree=Mozilla-Inbound&jobname=b2g_emulator_vm%20mozilla-inbound%20opt%20test%20crashtest-2&rev=ecbee0ea949e

(In reply to Ryan VanderMeulen [:RyanVM UTC-4] from comment #2) It's unlikely to be related to Waldo's patch AFAICS.

I agree with comment 3. That push was purely moving code around, no changes at all.

FWIW, I agree too or I would have backed this out a long time ago ;)
