Hi Jacek,

Technically, behavior is undefined if the pointers do not each point to an
object, even if the size parameter has a value of zero (see
http://tinyurl.com/6eqo3n, third post). Though I concede that it would be a
rare implementation that touched its pointers (or copies of them) in that
case.
