I get this issue compiling libcore when there are a lot of errors, as well.

[bltavares]

Triaging: I've checked out the repository on that exact commit and it does not ICE anymore.

rustc 1.8.0-nightly (15e9a95a4 2016-02-26)
cargo 0.9.0-nightly (ff4bda2 2016-02-25)

Now it causes an error because of incompatible types on an arm during macro expansions.
