[hkratz]

Is it reproducible with cargo clean; cargo build? If not it is likely a duplicate of #92163.

[Ppjet6]

It works with a cargo clean indeed.

I am able to repro this consinstently but my repo is not yet open.

cargo clean && cargo build -> change one line in a specific file -> cargo build -> ICE.

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 1.59.0-nightly (f8abed9ed 2021-12-26) running on x86_64-unknown-linux-gnu

note: compiler flags: -C embed-bitcode=no -C codegen-units=256 -C debuginfo=2 -C incremental --crate-type bin

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

query stack during panic:
#0 [typeck] type-checking `hacks::<impl at bwmapserver/src/hacks.rs:563:1: 563:28>::register::extract_chk_from_mpqs_where_chk_is_null`
#1 [analysis] running analysis passes on this crate
