Oh Gods, are we back to gcc people saying "sure, we do stupid things, but 
it's allowed, so we don't consider it a bug because it doesn't matter that 
real people care about real life, we only care about some paper, and real 
life doesn't matter, if it's 'undefined' we can make our idiotic choices 
regardless of what people need, and regardless of whether it actually 
generates better code or not".
