Comment 1 Josh Stone 2017-08-17 17:02:55 UTC 
I've reported this ICE already from a failing test case:
https://github.com/rust-lang/rust/issues/42757

I'll try to make it a higher priority if it will block firefox soon...
Comment 2 Josh Stone 2017-08-24 18:22:15 UTC 
It should be fixed in upstream rustc by this:
https://github.com/rust-lang/rust/pull/44066

If that merges soon, it will be in rust 1.21.  I can probably also backport it for 1.20 when that releases next week.
