The specification contains no requirements at all for that case. Which 
means that absolutely everything you might observe automatically fits 
the specification.

In other words, you're observing undefined behaviour.  And whenever that 
happens, that's a bug in your program, period.  So please do yourself a 
favour and stop worrying about what might have been nice, or what might 
happen on other platforms.  That's all missing the point.
