Error description

  • Instantiating a template using a type that was created with

    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);
    }
