Existing command `cargo +nightly fmt --all` now errors

[BrennerSpear]

I've been running this command (cargo +nightly fmt --all) all the time (daily+) and today it started spitting out this error

thread 'main' panicked at src/tools/rustfmt/src/parse/session.rs:40:9:

seems like it was a bad macro i wrote that gave it this issue

[ytmimi]

It looks like you're using an older nightly. Can you confirm if this is still an issue with the latest nightly? This reminds me of #6082, which has been resolved.
