Instead of memmoving N structs, we were memmoving N bytes. But why did the test pass then? It was doing memmove(..., 1) instead of memmove(..., sizeof(struct opt_table)! Because the two structures were really similar; the main difference was the first entry, which points to the name. But they were allocated consecutively, and Intel being little-endian, the only difference was the first byte! Thus memmove(1) was enough to make it "work". Change two options in the test to be sufficiently different, and the bug shows up. Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>
