/**
   Test: V_case4_i   - Assignment of shared pointers to private pointers.
   Purpose: To check the assignment of shared pointers to private ones.
   Type: Positive.
   How : - Define a shared integer data, a shared pointer and a private 
           pointer to integer.
         - Thread 0 assign the shared data a defined value.
         - Place a barrier. 
         - All threads assign the shared pointer to their private pointers;
         - The thread 0  should see the same value through their private pointers.
