/**
   Test: V_case4_ii   - Assignment of blocked shared pointers to 
                        private pointers.
   Purpose:
         To check the assignment of blocked shared pointers to 
         private pointers.
   Type: Positive.
   How : - Define a blocked shared pointer and a blocked shared array with the
           same blocking factor.
         - Define a private pointer. 
         - All threads assign the blocked shared pointer to an element of 
           the blocked array a.
         - Assign the blocked shared pointer to private pointer.
