Description

The upcoming testcase asserts js debug shell on m-c changeset b42615e51c81 (which contains the fix for bug 1117235) with  --fuzzing-safe --ion-offthread-compile=off --ion-eager at Assertion failure: !cx->isExceptionPending(), at jscntxtinlines.h

The shell was obtained from:

https://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/2015/01/2015-01-06-mozilla-central-debug/jsshell-linux-x86_64.zip

I cannot get a stack from the FTP builds as the builds from FTP do not have symbols. Further reduced testcases are extremely intermittent, but this seems fairly reliable.

Does not show the issue:

Not sure exactly what issue this is, so setting needinfo? from Terrence and Jan as a start.

Unfortunately I can't reproduce this (revision in comment 0, debug+opt build). I think the right thing to do here is to fix bug 1115005 first, that should hopefully make those bugs easier to repro.
