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 1.68.0-nightly (bdb07a8ec 2022-12-11) running on aarch64-apple-darwin

note: compiler flags: --crate-type lib -C opt-level=z -C panic=abort -C linker-plugin-lto -C codegen-units
=1 -C strip=symbols -Z print-type-sizes

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