[Bug c++/19625] New: GCC accepts a default value for the first argument of a template function

["Matthieu dot Moy at imag dot fr" <gcc-bugzilla at gcc dot gnu dot org>]

The following code compiles, and should not :

template<class T>
T f2(const char * s2, T arg2, T arg3);

template<class T>
T f2(const char * s2 = 0, // bug
     T arg2, T arg3) {
  return (s2)?arg2:arg3;
}


Same for the following :


template<class T>
class foo {
  T f2(const char * s2, T arg2, T arg3);
};

template<class T>
T foo<T>::f2(const char * s2 = 0, // bug
             T arg2, T arg3) {
  return (s2)?arg2:arg3;
}


Or for the even simpler


template<class T>
class foo {
  T f2(const char * s2 = 0, T arg2, T arg3); // bug
};
