Is this a gcc bug?

This would seem to imply that the behaviour is undefined because one
uses an undefined value. But that's not the case: the standard says
program behaviour is undefined even if you say x = ++x and never look
at x again. (At least IIRC.)

BTW, I would really like to mention the warning "sequence point" so
people have something to look up.
