I got this with what looks like a double ICE!

Maybe just a messaging bug? But also hilarious.

Not sure if dupe. Appeared on cargo test, reappeared (with less doubling) on reruns, disappeared on cargo clean.

Did you have feature(generic_const_exprs) enabled?

Yes.

I would expect #89113 has fixed this ICE then but it's a bit hard to tell

Probably! This can be closed for now, I will reopen it if it crops up again.

Not reopening since this is before the fix went in, but posting this RUST_TRACEBACK="full" just to make sure it's available.

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 1.57.0-nightly (ac2d9fc50 2021-09-21) running on x86_64-pc-windows-msvc

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C incremental --crate-type lib

note: some of the compiler flags provided by cargo are hidden
