This bug was filed from the Socorro interface and is 
report bp-af8e678b-15e8-44fa-8b5e-b877f2141027.
=============================================================

This is a new signature in nightly Fx 36 starting on 10/24. Most reports are from Windows 7 installations. There is no correlation data for add-ons. There was only one comment saying the person visited truthdig.com and the browser crashed. I wasn't able to reproduce this on a VM. This is in the list of top crashers at #28.

This may be related to bug 1091704. All of these are win64 but I suspect that's just due to inlining differences.
