Detailed Description
   template<typename _Tp>class __gnu_cxx::_Relative_pointer_impl< _Tp >
       A storage policy for use with _Pointer_adapter<> which stores the pointer's address as an offset value which is relative to its own
       address.

       This is intended for pointers within shared memory regions which might be mapped at different addresses by different processes. For null
       pointers, a value of 1 is used. (0 is legitimate sometimes for nodes in circularly linked lists) This value was chosen as the least likely
       to generate an incorrect null, As there is no reason why any normal pointer would point 1 byte into its own pointer address.
