   I can think of no good reason for wanting to do something like that. A   
   std::vector manages its resources internally which is why it can   
   relocate its elements. Indeed the implementation of std::vector is an   
   example of how to handle relocating data without having to keep an   
   external track of it.   
      
   However if you did do what your example suggests it would not cause a   
   problem because the vector does not move!! It is its internal data   
   storage that moves. Of course if you insisted on keeping a pointer to   
   one of its elements you would have a problem but that is something   
   different.
