From the stack, it kinda looks like we must have called nsLineLayout::ReflowFrame with a null frame pointer. But I can't seem to reproduce this locally at the moment.
Jason, does this reproduce for you with current trunk code, or has something changed such that it no longer happens?

Bugbug thinks this bug is a regression, but please revert this change in case of error.

This looks to have been fixed sometime within the following range:
Start: 7ea008f8701b6f95320a16d78ed6ed56e22235c6 (20181211162355)
End: a02122d22c5e3627c23591a77dde877961b44b8c (20181211162540)

Hmm, I don't see anything in that pushlog that looks particularly likely as a fix.... would you mind double-checking the range? I'd feel more confident in resolving this if we could point to where a relevant fix landed.

I can't reproduce this crash on Linux. It's very likely the same underlying issue as bug 1493775 though, which is reproducible.

Hey Jason,
Can you still reproduce this issue or should we close it?

I was unable to reproduce this issue using mozilla-central rev 152fdda295bb. I think we can safely close this issue.
