Undefined behavior according to WG14 but perfectly fine on most architectures. Even on architectures that don't support it (what the fuck ARM cortex) the compilers do support it.

Yes, that's exactly the point I've been making. It's undefined today because C has a type system and that type system has this arbitrary rule, not because there are implementation constraints necessitating it (where it could just be implementation defined instead).
