It's not perfect, but https://github.com/rust-lang/rust/issues?page=1&q=is%3Aissue... seems to indicate that we closed 81 issues tagged ICE between 1.0 and now. Not all of those made it into 1.1, bunches are in 1.2, and some of them are duplicates...

If you're running into ICEs or any other bug, please either open up a ticket or :+1: the ticket that exists. It helps to know which things are biting people more often.
