// 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.

s = append(s, empty{})
