Can't run linter goanalysis_metalinter: goanalysis_metalinter: unused: package "main" (isInitialPkg: true, needAnalyzeSource: true): internal error: unhandled case *types.Struct

[st6446]

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 (e.g., gocritic, go vet, etc.). (https://golangci-lint.run/usage/linters/)

Description of the problem

Bumping golangci-lint v1.51.1 from v.1.15.0, and execute golangci-lint. Then error happend.

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

Hello,

can you provide a minimal reproducible example?

You have checked the following box:

[x] Yes, I've tried with the standalone linter if available (e.g., gocritic, go vet, etc.). (https://golangci-lint.run/usage/linters/)

unused is related to staticcheck, can you give me the output of the run of the standalone binary of staticcheck? (golangci-lint v1.51.1 uses honnef.co/go/tools@v0.4.0)

https://github.com/golangci/golangci-lint/blob/v1.51.1/go.mod#L115

I think the problem is already fixed by #3591 but you have to check.

This is indeed a staticcheck issue, reported here dominikh/go-tools#1361
