C-bug Category: This is a bug. glacier ICE tracked in rust-lang/glacier. I-ICE Issue: The compiler panicked, giving an Internal Compilation Error (ICE) ❄️ P-medium Medium priority regression-from-stable-to-beta Performance or correctness regression from stable to beta. T-compiler Relevant to the compiler team, which will review and decide on the PR/issue.

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/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.64.0-nightly (20a6f3a8a 2022-06-25) running on x86_64-unknown-linux-gnu

query stack during panic:
#0 [typeck] type-checking `main`
#1 [typeck] type-checking `main::{closure#0}`
#2 [typeck_item_bodies] type-checking all item bodies
#3 [analysis] running analysis passes on this crate
end of query stack

fn main() {
    (|_, ()| ())([return, ()]);
}

This does not ICE on stable 1.62.0 but ICEs on
Beta version: 1.63.0-beta.3 (2022-07-02 59f577d) and
Nightly version: 1.64.0-nightly (2022-07-03 495b216)
