Volume:
678 crashes in the last week (#12 DOM crash @ 1.01%)
Platforms:
All crashes on Windows with 77% on Windows 7 32-bit
Products:
64% on Firefox 36
35% on Firefox 37
1% on Firefox 38
0% on Firefox 39
I'm marking this as a regression in Firefox 36 based on crash-stats but I don't have any solid leads as to how to reproduce this or what might have caused it.

Looks like a null pointer crash, but what exactly is null... perhaps CurrentGlobalOrNull returns null
since WindowGlobalOrNull can't deal with that?
But anyhow, probably a regression from bug 1070842
Bobby, since you were the developer involved with bug 1070842, would you be able to look into this?

Smaug's theory sounds reasonable - I don't think we're in a compartment when tokenizing. Waldo, can you confirm?

I think we're in a compartment when tokenizing. There's pretty little you can do when you're *not* in a compartment, and not being in one would make it very, very difficult (probably impossible) to do things like create template objects. So I rather doubt that's the explanation, but I could be wrong.

Ok - hopefully anthony can tell us if the signature goes away.

We have a few crashes for Aurora 38 and Nightly 39 in the last few days but they're with builds before the fix landed. I see no crashes with "fixed" builds. That said, volume was initially low with 38 and 39 so I'm not confident that I'll be able to 100% confirm this is fixed without a reproducible testcase.
We should know more when Firefox 38 moves further into the Beta cycle. I can put a reminder in my calendar to loop back in a couple weeks.
