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

note: we would appreciate a bug report: https://github.com/rust-lang/rust-clippy/issues/new?template=ice.yml

note: please attach the file at `/home/gh-matthiaskrgr/vcs/github/rust_icemaker/rustc-ice-2024-03-16T09_08_43-265551.txt` to your bug report

query stack during panic:
#0 [analysis] running analysis passes on this crate
end of query stack
note: Clippy version: clippy 0.1.78 (c563f2e 2024-03-16)

[Noratrieb]

that's expected, the float types are still being added and will panic, please don't fuzz them yet.

[matthiaskrgr]

the file is from the rustc repo, have you not read the ticket?

[Noratrieb]

Yes, the file tests that float name resolution works. A lot of areas, including clippy, are stubbed out with todo!() for now, so it's expected that clippy would die on such a file.
