    This will probably make a simple cargo build crash in a lot of cases :3

    Hmm, when writing #120943 I tried to trigger the opt_hash_including_bodies.unwrap() case by enabling -Cincremental, but it didn't ICE.
    I'll check what is the difference with what cargo does.

    A workaround to this issue should be to use cargo check --release or cargo build --release which should disable incremental compilation.

    run cargo test on nightly rust also [ICE: compiler/rustc_hir/src/stable_hash_impls.rs None with cargo build of async fn in trait](https://github.com/rust-lang/rust/issues/122508#top) #122508

    but. if you use rustup default stable to switch stable version rust
    will be run cargo test will successful

    …which should disable incremental compilation.

    There’s also an environment variable to control incremental compilation, so you could set CARGO_INCREMENTAL=0 to do that.

    I think this error should be completely fixed, otherwise it will still fail to compile in the IDE environment and the automatic build environment of GitHub Action

    Sure, we were just offering a workaround to unblock people temporarily. The fix is already present on master and should be available in tomorrow’s nightly.
