Non-fatal error while running a specific cargo check command

[Kiwifuit]

Code

I'm sorry I cannot provide a minimal code example as I am equally confused with this issue. However, I have tried this and it produces the error.
The original repository can be found here

I am using rust-analyzer v0.3.2045 with the command it spat out:

cargo check --workspace --message-format=json-diagnostic-rendered-ansi --manifest-path <Cargo.toml> --keep-going --all-targets

No error is produced with cargo check, just with these specific flags

Does this issue persist after you do cargo clean or does it go away? Some things like this are cache-related.

This issue only happens with the stable build

Meaning the issue doesn't show up on nightly?

Yes, i have tried this command:

cargo +nightly check --workspace --message-format=json-diagnostic-rendered-ansi --manifest-path <Cargo.toml> --keep-going --all-targets

[tgross35]

It goes away

Does it stay away, or is does running your command make it happen again?

This ICE is due to an incremental compilation file which is corrupt, probably because it was damaged by another process. This scenario seems to be so frequent that I've turned the ICE into a warning with a recovery path that just ignores the file. That change is in 1.80, which will be stable tomorrow.

[saethlin]

As far as I can tell, the ICE reported in this issue is caused by another process damaging rustc's build artifacts or by a buggy filesystem. That other process could be anything from an IDE running the compiler at the same time as a manual build to a find-and-replace that accidentally edits files in the target directory.

#124686 contains a mitigation for this situation; the compiler now has a crude way to detect and ignore damaged incremental compilation files. You will still get a warning about the damaged file, but the build should proceed normally. That change shipped in Rust 1.80 which released today, so I am closing this issue and a few others which as far as I can tell all have the same root cause. You shouldn't see this ICE anymore, but please file a new issue if you see something like it on 1.80 or later.
