APAR status

• Closed as program error.

Error description

• The following test case produces a template argumemt miss-match
  when it shouldn't.
  
  
  ===== Compile Command:
  bgxlC_r -c simple.cpp
  
  
  ===== TESTCASE:
  $cat test.cpp
  
  template<typename T,typename Int=int>
  class Foo;
  
  template<typename T>
  class Foo<T>
  {
  public:
      void Bar() const;
  };
  
  template<typename T>
  void Foo<T>::Bar() const
  {}
  
  int
  main( int argc, char* argv[] )
  {
      Foo<double> foo;
      foo.Bar();
  
      return 0;
  }
  $
  
  
  ===== ACTUAL OUTPUT:
  $bgxlC_r -c test.cpp
  "test.cpp", line 14.6: 1540-0708 (S) The template argument 2
  does not match the corresponding template parameter of "template
  class Foo".
  
  ===== EXPECTED OUTPUT:
  Should compile clean
  

Local fix

• n/a
  

Problem summary

• USERS AFFECTED:
  The problem may be seen when a member of a partial
  specialization is defined out-of-line and the specialization
  uses a default template parameter argument.
  
  PROBLEM DESCRIPTION:
  Incorrect name lookup results in bad argument mismatch error.
  

Problem conclusion

• The compiler has been resolved to take care of the above case.
  

Temporary fix
