Crash Data

This bug was filed from the Socorro interface and is 
report bp-40bae183-723b-4200-a3ec-627de0171103.

This is the #6 windows topcrash in Nightly 20171103100331. The crashes are coming from relatively few installations.

Crash address is always 0x0, looks like `viewport` is nullptr.

First sign of it in Nightly is in build 20171101104430, which suggests this regression range:

Having said that, the frequency took a jump in build 20171103100331, which corresponds to this regression range:

dvander, you have some patches in the first regression range from bug 1395478, could this be related?
