/**
   Test: V_case5_i - Assignment of shared-pointers-to-shared to 
                     private-pointers-to-shared with different 
                     blocking factors. 
   Purpose: To check that the phase becomes 0 and that pointer arithmetic 
          obeys the original type of the shared pointer to be manipulated. 
   Type: Positive.
   How : - Declare two blocked shared pointers to integer, with different 
           blocking factors,
         - Do the Cast.
         - Check that the phase is equal to 0, for the assigned pointer.
         - Increment the pointer by a certain value.
         - Check the pointer value, through the use of upc_addrfield().
