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 1.57.0-dev running on x86_64-unknown-linux-gnu

note: compiler flags: -Z macro-backtrace -Z tls-model=initial-exec -Z binary-dep-depinfo -C opt-level=3 -C embed-bitcode=no -C debuginfo=1 -C debug-assertions=on -C incremental -C link-args=-Wl,-rpath,$ORIGIN/../lib -C llvm-args=-import-instr-limit=10 --crate-type lib

Hmm, this may be a duplicate of #76720.

[jyn514]

Running rm -r build/x86_64-unknown-linux-gnu/stage1-tools fixed this issue so I think this is indeed an issue with using -dev instead of the git hash.
