  // Issue 10135: append a slice with zero-sized element used
  // to always return a slice with the same data pointer as the
  // old slice, even if it's nil, so this program used to panic
  // with nil pointer dereference because after append, s is a
  // slice with nil data pointer but non-zero len and cap.
  package main
  type empty struct{}
  func main() {
  	var s []empty
  	s = append(s, empty{})
  	for _, v := range s {
  		_ = v
