ICE when compiling with `RUST_LOG=rustc::middle`

[hirschenberger]

ICE when compiling a simple program with RUST_LOG=rustc::middle. It does not crash when using RUST_LOG=rustc::middle::trans.
It also depends on the program being compiled if it crashes or not.

Smaller example:

fn main() {
    ::std::fmt::argument({loop{}}, &1i);
}

Compile with RUST_LOG=rustc::middle::astencode

fmt does some crazy things with &Void, and it shows up in the log, so it may be related.

This still ICEs for me.

Can't reproduce anymore with rustc 1.0.0-nightly (c9b03c24e 2015-03-12) (built 2015-03-13)

[Stebalien]

Can't reproduce either rustc 1.1.0-nightly (c033d9828 2015-05-09) (built 2015-05-09)
