Thank you for opening a report but please extract and post the relevant portions of the log inline within the issue so it's easier for everyone to consume and reference (e.g. so that others can more easily know if this is the same issue they encountered, and avoid opening duplicative tickets)

[RustyYato]

edit: I did a more detailed comparison on the stack traces, and it's different, but maybe there's a similar issue? If not I can open a separate ticket for this

I ran into the same issue (same stack trace too as far as I can tell), and here's a MVP

macro_rules! bz {
    () => {
        match foo {
            _ => return bar;
        }
    };
}

There is no other context needed, but switching the ; after bar to a , doesn't ICE, so I suspect this may be due to failure to handle invalid syntax in a macro? If it's outside the macro then there's also no ICE.

@RustyYato I believe you're running into the same issue. Both backtraces start with:

thread 'main' panicked at src/tools/rustfmt/src/parse/session.rs:42:9:
silent emitter attempted to translate a diagnostic

Which leads me to believe this is a duplicate of #6082
