thread 'rustc' panicked at 'index out of bounds: the len is 681 but the index is 682'

Code

The backtrace however, contains some useful information like "index out of bounds", for those who knows the implementation of the compiler. I guess it should be a good clue to find out what makes it wrong.

error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

[compiler-errors]

Can you check if this is fixed on nightly?

[earthengine]

@compiler-errors
Running the nightly channel on the same code reports a type error that linked to a change I made in the code that making a function returning Result<T, E> to an async fn but forgot to change the calling site to use .await.

[earthengine]

Ok, according the clue above I found a minimal code example

async fn foo() -> Result<(), String> {
    Ok(())
}

fn convert_result<T, E>(r: Result<T, E>) -> Option<T> {
    None
}

fn main() -> Option<()> {
    convert_result(foo())
}

Playground

The above code should not compile; but instead of reporting errors it crashes the compiler.

Seems only affects the stable channel; beta and nightly are working properly.

(The example code can be rewritten as foo().ok() or something like that and it will report the error correctly; however the real code was converting to ControlFlow instead of Option so it does not help)

[compiler-errors]

So this is fixed by #99928 -- unfortunately that's going to land in the next release cycle (1.65) and this isn't a critical enough ICE to warrant a patch release for 1.64

[estebank]

@compiler-errors can we add the repro to the test suite and close the ticket then?

[Rageking8]

@rustbot claim
To add the test if it's not already done.

[compiler-errors]

Please do!
