January 2006 XL C/C++ Enterprise Edition V7.0 for AIX PTF

APAR status

• Closed as program error.

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

• n/a
  

Problem summary

• Compiler incorrectly flags the construct in question.
  

Problem conclusion

• Compiler has been corrected to handle the construct per
  language standard and it will not give diagnostic message any
  further.
  

Temporary fix
