All those crashes seem to have a 0x0 address and almost all are on startup and on Windows 7.
On m-aurora, it looks like bug 1159751 is the one gfx patch that landed in the offending timeframe and it matches the #1 frame. Bas, do we need to back out?
Yes. This was bug 1159751. I can fix it.
Bug 1159751 has been backed out per IRC discussion with Jeff and Windows nightlies are being respun.
Thanks for backing this out so quickly.
This was mentioned as a top crash in today's channel meeting.
I believe this is also showing up in the form of busted Marionette tests on a particular Windows 7 builder that belongs to Platform Quality: https://treeherder.mozilla.org/#/jobs?repo=mozilla-central&revision=72835344333f&filter-job_group_symbol=VP&filter-platform=Windows%207 Here's a crash report sent from that builder: https://crash-stats.mozilla.com/report/index/6b83bf98-37ee-4291-923c-0ad8b2150715
Last reports of this crash were with builds from 2015071603. VERIFIED per crash stats.
