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

Code:

package main

import "fmt"

func main() {
	c := a("hello linter", b[string])
	println(c)
}

func a[T any, N any](x T, y func(T) N) N {
	return y(x)
}

func b[T any](x T) string {
	return fmt.Sprint(x)
}
