ICE during clippy

[gzp79]

I'm not sure what modification I had in the code, but compiler failed win an internal error (see below), but after a cargo clean all was working again.

(I don't know if it is relevant but my modification before the failure were marking a trait (and it's implementation) unsafe related and adding a few panic related comments.)

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust-clippy/issues/new

note: Clippy version: clippy 0.1.58 (e99963c5 2021-10-29)

query stack during panic:
#0 [analysis] running analysis passes on this crate
end of query stack

This seems to be a rustc issue, not clippy, and be related to rust-lang/rust#89962.

[giraffate]

It seems to be rustc issue, so I'm closing this.
