Comment(by Richard Webb <richard.webb_at_[hidden]>):

 In VC9, the copy code does the check

         _DEBUG_RANGE(_First, _Last);
         if (_First != _Last)
                 _DEBUG_POINTER(_Dest);

 Wheras VC10 just does

         _DEBUG_RANGE(_First, _Last);
         _DEBUG_POINTER(_Dest);

 (Where _DEBUG_POINTER gives an error if _Dest is NULL).
 So VC9 only complains if Dest is null and theres something to do, but VC10
 gives you an error any time it's null.
