IV33368: TEMPLATE AND TYPEDEF CAUSING INTERNAL ERROR

February 2013 PTF for XL C/C++ for AIX, V11.1

APAR status

• Closed as program error.

Error description

• Instantiating a template using a type that was created with
  typedef is causing the compiler to encounter an internal
  compiler error.
  
  
     ===== TEST CASE =====
  
  template< typename T,
            typename TypeDefType = typename T::typedeftype,
            TypeDefType (T::*Val)() = &T::val >
  struct myStruct
  {
   static TypeDefType run( T & g )
   {
    TypeDefType n = (g.*Val)();
    return n;
   }
  };
  
  class A {};
  
  class B
  {
   public:
    typedef A * typedeftype;
    A * val() { }
  };
  
  void set(...);
  
  void test()
  {
   typedef B C;
   set(&myStruct<C>::run);
  }
