[Bug c++/32322] New: pointers to overloaded methods not correctly resolved

["mavdzee at yahoo dot co dot uk" <gcc-bugzilla at gcc dot gnu dot org>]

In a template-context, pointers to overloaded methods are not correctly
resolved. the following main.cpp does not compile on gcc 4.1.2, however it does
compile on version 3.4.6:

#include <boost/multi_index_container.hpp>
#include <boost/multi_index/member.hpp>
#include <boost/multi_index/composite_key.hpp>
#include <boost/multi_index/mem_fun.hpp>

namespace mi = boost::multi_index;

struct field_ts
{
  int ts() const { return 10; }
  void ts(const int &arg) {  }
};;

template <typename T>
struct mi_key
{
  typedef typename mi::composite_key<
    field_ts,
    mi::const_mem_fun<field_ts, int, &field_ts::ts>
   > type;
};

mi_key<int>::type  key;

int main (int argc, char **argv)
{
  return 0;
}

I get the following error-message:

main2.cpp: In instantiation of ?mi_key<int>?:
main2.cpp:26:   instantiated from here
main2.cpp:23: error: invalid use of ?field_ts::ts? to form a
pointer-to-member-function
main2.cpp:23: note:   a qualified-id is required

The compiler should do this automatically without you having
to disambiguate the overload, see 14.3.2/5:

"For a non-type template-parameter of type pointer to member
function, no conversions apply. If the template-argument represents
a set of overloaded member functions, the matching member
function is selected from the set (13.4)."
