error: 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: please attach the file at `/h/344/drehwald/prog/rust/library/autodiff/rustc-ice-2023-11-07T04_12_42-2990359.txt` to your bug report

note: compiler flags: -C opt-level=3 -C lto=fat

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