But I can't reproduce it

type (
	Issue23A struct {
		b *Issue23B
		v int64 `vd:"$==0"`
	}
	Issue23B struct {
		a *Issue23A
		v int64 `vd:"$==0"`
	}
)

func TestIssue23(t *testing.T) {
	var data = &Issue23B{a: &Issue23A{b: new(Issue23B)}}
	err := vd.Validate(data)
	assert.NoError(t, err)
}

=== RUN   TestIssue23
--- PASS: TestIssue23 (0.00s)
PASS
