    Add virtual qualifier to derived Operation class destructors
    
    When a base class destructor is virtual, derived class destructors are
    also virtual [1] even if they don't have the virtual qualifier.
    
    As the Operation destructor is virtual, derived Operation* classes
    destructors are virtual too.  Add virtual qualifier just to reflect what
    the C++ language mandates the compiler implement.
