No, we didn't -- any valid pointer can be converted to a pointer that has less strict alignment and back, so that the result compares equal to the original pointer, void* has the same alignment requirement as char*, and converting a coarsely-aligned malloc() void* to OBJ* does NOT result in adjustment of the alignment. Apply ALL the relevant constraints and you'll find that there is no problem with typical malloc()/free() usage.
