Aha.  That sounds good to me; I don't expect your testcase to work, because it
doesn't involve a char buffer.  The copy does need to use the object
representation, but I think the new-expression should be undefined (though the
standard needs fixing to make it so--this is core issue 1027).

So, can we revert the function::swap change for 4.6, then?
