7// Issue 10135: append a slice with zero-sized element used
8// to always return a slice with the same data pointer as the
9// old slice, even if it's nil, so this program used to panic
10// with nil pointer dereference because after append, s is a
11// slice with nil data pointer but non-zero len and cap.
