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 1.66.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: -Z treat-err-as-bug

query stack during panic:
#0 [mir_borrowck] borrow-checking `main`
#1 [analysis] running analysis passes on this crate
end of query stack

[aliemjay]

Debugging leads to #102052, but I'm still surprised that we don't catch this during HIR typeck.

[matthiaskrgr]

Is this a duplicate of #79590 ? the stackrace looks very similar (also look who claimed that one :P 🙈 )

[lcnr]

^^ not sure, can't tell without looking deeper
