That's another kettle of fish :-) The standard allows the
optimization, which means you must never rely on the copy constructor
being (not) called. And a copy constructor must simply create copies
of objects. In any case, it's annoying when you want to observe what
the copy constructor does in a given scenario and you can't set a
breakpoint in it because it is not even called. I have often felt the
need to turn the optimization off during debugging.
