In fact, it is not a minimal example. I will come back with one later.

[faucct]

Okay, this reproduces the error, though Arc::new(FooImpl {}).foo().await has to be in a different file. FooImpl::test().await works fine.

pub trait Foo {
    async fn foo(self: &(impl std::ops::Deref<Target=Self> + Clone + Send + 'static));
}

pub struct FooImpl {
}

impl Foo for FooImpl {
    async fn foo(self: &(impl std::ops::Deref<Target=Self> + Clone + Send + 'static)) {
    }
}

impl FooImpl {
    pub async fn test() {
        Arc::new(FooImpl {}).foo().await;
    }
}

error: 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

[faucct]

I have updated to the latest nightly and this has been fixed:

nightly-aarch64-apple-darwin updated - rustc 1.71.0-nightly (4a59ba4 2023-05-12) (from rustc 1.71.0-nightly (fec9adc 2023-04-21)).

[bugadani]

I'm guessing this was fixed by #111039
