As it explicitly places no requirements on a compiler faced with code including undefined behaviour I can see no reason (from the Standard) why a stupid implementer should not do something malicious. Of course he will not have any customers but that is something else. The Standard does not grant any rights with regard to code including undefined behaviour, it simply disowns it places no requirements on implementers.
