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...
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.
