mm_map_aux() takes in |b._b| which can end up reallocating |km| at the end of mm_map_frag_core(). Since the address of |km| is cached before those calls it ends up pointing to freed memory. This can result in a crash as seen in #1183, however it also happens to Just Work most of the time since the new allocation often lands at the same address as the old one. Preloading ASAN or a similar replacement allocator that doesn't have that behaviour results in a reliable crash.
