@sinitcin thanks for the report. We've got a few SourceAnnotation panics that are all related, so my initial gut feeling is that this is a duplicate, but I'd need some more info to know for sure. What version of rustfmt were you using? Also, can you run cargo fmt -- -v. and post the output. That might give us a better idea of what file rustfmt was reformatting when it panicked!

Seems to be a bug caused by rustfmt supplying a byte-index while annotate-snippets expects a char-index, because of the cyrillics they're different, I made a PR for it here #6084
