IZ76017: XLC ACCEPTS TEMPLATES WITHOUT ARGUMENT LIST

October 2010 PTF for XL C/C++ for AIX, V10.1

APAR status

• Closed as program error.

Error description

• For the following reduced test case where the template has no
  argument list, xlC compiler accepts it and does not give out
  error message.
  
  
  struct container{
     template <class A, class B> struct inner;
  };
  
  struct tester : public container {
     friend class container::inner;
  };
  
  xlC
  clean compile
  
  
  It should give out errors similar to:
  
  b.cpp:8: error: invalid use of template-name 'container::inner'
  without an argument list
  b.cpp:8: error: friend declaration does not name a class or
  function
  

Local fix
