Testcase to show problem

Problem: call to public member function catalog failed on Linux -std=c++03 or
-std=c++11 using g++/5.1.0.
         Same exercise passed with g++/4.9.2.

% cat t.c
#include <locale>
#include <string>
#include <stdio.h>

template <class charT> class D : public std::messages<charT> {
public:
  D() {};
  std::messages_base::catalog func00(const std::basic_string<char>& name,
      const std::locale& loc) {
    return std::messages<charT>::do_open(name, loc);
  };

  typename std::messages<charT>::string_type
     func02(std::messages_base::catalog cat, int set, int msgid,
  const typename std::messages<charT>::string_type& dfault) {
    return std::messages<charT>::do_get(cat, set, msgid, dfault);
  };
};

int main()
{
  D<char> dchar;
  const std::basic_string<char> name;
  const std::locale loc00;

  int n1 = dchar.open(name, loc00);
  int n2 = dchar.func00(name, loc00);
  if (n1 != n2)
    printf("Failed: n1 = %d, n2 = %d\n", n1, n2);
  else
    printf("Passed: n1 = %d, n2 = %d\n", n1, n2);
} 

#-----------------------------------------------

return code from g++: 0

--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
I see a change in behaviour between gcc-4_9_3-release and gcc-4_9-branch, but
I'm not sure how.
