go-critic/ruleguard: unreachable

[pierrre]

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

When I run golangci-lint on a package that contains generic code, the go-critic/ruleguard linter panics with the message "unreachable".

Version of golangci-lint

$ golangci-lint --version
golangci-lint has version 1.49.0 built from cc2d97f3 on 2022-08-24T10:24:37Z

Configuration file

$ cat .golangci.yml

• Yes, I've tried with the standalone linter if available.

Do you have the output of go-critic as a binary?

[pierrre]

So it's a go-critic issue ? 😄

[ldez]

yes 😸

[pierrre]

So it's go-critic/go-critic#1219

[pierrre]

Sorry, my bad, I thought go-critic was fully functional with generics 😞

[pierrre]

Sharing some updates go-critic/go-critic#1253

[pierrre]

For now my quick fix is to disable the externalErrorReassign rule in go-critic config.
