            Bug ID: 60916
           Summary: truncated error message
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: tromey at gcc dot gnu.org

Compile this program:

int f(char *);

const char *get_something ();

template<typename T, int (*F) (const T *)>
int wrapper ()
{
  return F (get_something ());
}

template<typename T1, typename T2, int (*F) (const T1 *, const T2 *)>
int wrapper ()
{
  return F (get_something ());
}

int docall ()
{
  return wrapper<char, f> ();
}


I get:

The trailing ":" implies to me that more is to come -- but the
messages stop here.
