That is a rustc bug. Please downgrade your nightly.

This isn't hasn't been fixed since this was closed over a month ago, and if I'm reading correctly, it doesn't look like Rust has any open issues to address. Should we just fix the issue here instead of permanently staying on an old version of rust? I believe the fix should be just... adding three type annotations?
