[y21]

Moved to the rust repo because this doesn't look like a clippy ICE: this also reproduces simply with cargo check in the libafl_libfuzzer/libafl_libfuzzer_runtime crate.

[addisoncrump]

Yup, I ICE'd out on CI just now. Whoops.

[lqd]

The rustc 1.77.2 (25ef9e3d8 2024-04-09) version in the OP should not trigger this ICE, which is on nightly since yesterday only, but yeah it's most likely a duplicate of https://github.com/rust-lang/rust/issues/124054 and will be fixed by #124066
