No, I would respectfully point out you're wrong, read the links in comment 1. 
Undefined behaviour doesn't just mean "the standard omits to mention what
happens" it means *anything* can happen. That includes different behaviour
every time you run the program (think of accessing uninitialized data that
contains random junk values) or setting your monitor on fire or wiping your
hard drive. You should not have *any* expectations of undefined behaviour.
