Compiler crash

[AlterionX]

The compiler crashed and told me to report it.

I shaved off the excess and found this to be a minimally working (breaking) example:
https://play.rust-lang.org/?version=stable&mode=debug&edition=2018&gist=10a2d80c7a36cc12edaa39cd3d6a5781

I expected it to tell me that the T in a::<'_, T> is an error.

Thanks for the report and the small example!

This is possibly a duplicate of #60622

Jup, this one also regressed between 1.29.2 and 1.30.0, so I'll close this as a duplicate of #60622
