:jonco, it appears that your change from bug 930414 is causing this leak about 75% of the time:
https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&filter-searchStr=bc7%20osx%20debug%2010.10&fromchange=0bcf20224e95&tochange=db71bd216371

related bugs would be bug 1217332, and bug 1217654

Can you take a look at this?  Right now we have this test disabled as of yesterday.  This is a problem on osx 10.10 (both 10.10.2 and 10.10.5)

[Jon Coppeard (:jonco)]

I haven't been able to reproduce this.  The test passes when run locally.

I ran the test under valgrind and it produced many warnings but none that seemed to be related to JS (I filed bug 1221055 for that).

I saw this happen on try over and over again, likewise on the trees.  Most likely we have a different version of osx on our automation boxes than you have locally.  Maybe there is some other network condition or setup which is causing the difference.

Loaners are easy to get and not much trouble to work on assuming you can vpn in.  The biggest problem one could expect is lack of familiar tools, source tree, and build environment.

[Jon Coppeard (:jonco)]

I've got access to a loaner and run the test on the build linked above, but so far it has passed every time.  Will investigate more tomorrow.

Given the timeframe and the latter part of the backtrace, I'm going to say that this is the same issue as bug 1217332.
