rustc 1.79.0-nightly (5f2c7d2bf 2024-03-25)
binary: rustc
commit-hash: 5f2c7d2bfd46cad00352ab7cd66242077e2e518c

release: 1.79.0-nightly
LLVM version: 18.1.2

The crash is present in nightly but not in beta, as in beta works fine.

Something that might be important is that running cargo build results in the following error:

error[E0635]: unknown feature `stdsimd`
  --> C:\Users\anton\.cargo\registry\src\index.crates.io-6f17d22bba15001f\ahash-0.8.6\src/lib.rs:99:42

   |                                          ^^^^^^^

For more information about this error, try `rustc --explain E0635`.
error: could not compile `ahash` (lib) due to 1 previous error
warning: build failed, waiting for other jobs to finish...

Found this thread that explains the error.

This is not an issue for me as I manually bumped the versions of some of my dependencies which fixed both issues but this seems like a weird edge case in cargo (unless I missed something).

This has been fixed and is expected to release with the next nightly. See rust-lang/cargo#13646.

Closing with rust-lang/cargo#13646 as the root cause.
