3 years ago I've also seen this ICE on:
rustc 1.57.0-nightly (d7c97a02d 2021-10-12)
binary: rustc
commit-hash: d7c97a02d1215e4ef26c31cb72dbaf16fd548b2c
commit-date: 2021-10-12
host: x86_64-unknown-linux-gnu
release: 1.57.0-nightly
LLVM version: 13.0.0It was reproducible with the same cache state, but it was resolved by clearing the cache.
Here is the backtrace:
```

What I tried
cargo updateas of today updated the dependencies to a state that seem to circumvent the ICE.Without the cargo update, using beta the ICE does not occur.
Also without the cargo update, using nightly the ICE does not occur.
What solved it
Deleting the target folder (after reverting the cargo update) fixed the ICE. I could then run
cargo testagain and no ICE occurred.I might have clicked the test button too fast in my IDE while debugging, so possibly cargo was run concurrently.
