Error description

  • Compiler reports error for the following test case. It compiles
    fine if a scalar int is used.
    
    
    typedef int IntArray[2];
    
    void fakeFunc(IntArray &) { }
    
    void constCastArray() {
       const IntArray i = { 1, 2 };
       fakeFunc(const_cast<IntArray &>(i));
    }
    
    $ xlC const_int_array_test.cxx
    "const_int_array_test.hxx", line 5.41: 1540-0216 (S) An
    expression of type "const IntArray" cannot be converted to type
    "IntArray &".
    

Local fix
