Sorry, not a very helpful bug report, but it said to open an issue

No worries. What version of rustfmt are you using?

@aDifferentJT

@aDifferentJT Do you also have an input snippet that we could run rustfmt on to reproduce the issue?

The latest nightly, I ran rustup update about an hour ago.

Not to hand unfortunately, I haven't yet tried to narrow down the code that causes it, I'll try to do that in the morning, it's quite late here.

@aDifferentJT

@aDifferentJT I don't think this is an issue with a particular code snippet. If I had to guess Id say changes made in rust-lang/rust#121085 are causing this issue.

were you running rustfmt on a public repo? That might be enough to reproduce the issue.

Sorry, no, it's private for now, if I get time in the morning I'll try to get a more minimal case I can send

I've minimised the file, this seems to be the smallest file that causes the issue

rustfmt_ice.rs

macro_rules! test {
    ($T:ident, $b:lifetime) => {
        Box<$T<$b>>
    };
}

Perfect! I'm also able to reproduce the bug using the snippet. Thank you very much! I think this will help us figure out what's going on.

rust-lang/rust#121487 doesn't explicitly reference this issue, but I'm hoping that it also resolves the problem 🤞🏼

Rollup merge of rust-lang#121301 - davidtwco:rustfmt-silent-emitter, …

Unrolled build for rust-lang#121301

@aDifferentJT

@aDifferentJT when you have a moment can you confirm that this is resolved on the latest nightly (rustfmt 1.7.0-nightly (7d3702e4 2024-03-06)? I just ran your input snippet with a few recent nighty versions, and I can no longer reproduce the panic using the most recent nightly.

steps to verify:

rustup install nightly or rustup install nightly-2024-03-07
rustfmt +nightly

@ytmimi

@ytmimi Looks like it's working, thanks
