I can reproduce the crash; will investigate.

[dominikh]

Reproducer:

package merkle

type Tree[T any] struct {
	Root *Node[T]
}

type Node[T any] struct {
	Tree *Tree[T]
}

func (n *Node[T]) anyMethod() {}

[ainar-g]

Possibly the same as golang/go#51832?

[dominikh]

@ainar-g Unfortunately not. This is a bug in U1000's own logic.

[dominikh]

Fixed on master, will be part of next week's 2022.1.1 release.

FYI: the issue is reproducible with GitHub Actions dominikh/staticcheck-action@v1.2.0 if major version is used

      - uses: dominikh/staticcheck-action@v1.2.0
        with:
          version: "2022.1"
          install-go: false

as fix, use either latest or version: "2022.1.2"
