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 1.69.0-nightly (5e37043d6 2023-01-22) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib -Z validate-mir

query stack during panic:
end of query stack

Anything else?

This requires -Zvalidate-mir!

Minimized out of #107051
