Using `--fix` with both `gofumpt` and `gocritic` linters deletes comment lines

[psaikko]

Welcome

• Yes, I'm using a binary release within 2 latest major releases. Only such installations are supported.
• Yes, I've searched similar issues on GitHub and didn't find any.
• Yes, I've included all information below (version, config, etc).
• Yes, I've tried with the standalone linter if available. (https://golangci-lint.run/usage/linters/)

Description of the problem

Using golangci-lint with --fix flag and both gofumpt and gocritic linters enabled deletes comment lines.
This is the case with at least comment lines missing a space after //.

In minimal example running with golangci-lint run --fix --disable-all --enable gocritic,gofumpt with no .golangci.yml config file.

Using either gofumpt or gocritic alone has the expected behavior (e.g. adding whitespace after //)

Version of golangci-lint

Hey, thank you for opening your first Issue ! 🙂 If you would like to contribute we have a guide for contributors.

I ran into this as well. It was fairly hard to add a comment to the code with this

[DryHumour]

I wonder if the issue might be triggered in general by two or more fixers being applied to the same line?

[ldemailly]

so per the closed dup issue, not just comments but also code

Fixed by #3230
