Unfortunately I don't have a minimal reproduction for this 😞

[Turbo87]

also FWIW cargo build appears to work fine, but only cargo test causes the ICE

[steffahn]

I can reproduce getting an ICE with

git clone https://github.com/Turbo87/crates.io.git
cd crates.io
git checkout ice
cargo check --test all
git checkout HEAD~1
cargo check --test all

[steffahn]

I’ve started some reduction work:

git clone https://github.com/steffahn/crates.io.git
cd crates.io
git checkout one
cargo check
git checkout two
cargo check

(edit: there’s a full MCVE below; this fork will be deleted eventually)

Interestingly, this reduced example’s ICE looks slightly different, I just noticed:

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 1.63.0 (4b91a6ea7 2022-08-08) running on x86_64-unknown-linux-gnu

note: compiler flags: --crate-type lib -C embed-bitcode=no -C debuginfo=2 -C incremental

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

query stack during panic:
#0 [evaluate_obligation] evaluating trait selection obligation `(): AsQuery`
#1 [typeck] type-checking `foo`
#2 [typeck_item_bodies] type-checking all item bodies
#3 [analysis] running analysis passes on this crate
end of query stack
