error: aborting due to 11 previous errors; 2 warnings emitted

Some errors have detailed explanations: E0405, E0412, E0573, E0601, E0658.
For more information about an error, try `rustc --explain E0405`.

Can't repro this either, @matthiaskrgr. Maybe it stopped ICEing, or maybe it wasn't minimized correctly?

[matthiaskrgr]

Looks like its fixed 🙂
