// 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. | |
