             Bug #: 15169
           Summary: unhandled overload resolution case
           Product: gdb
           Version: unknown
            Status: NEW
          Severity: normal
          Priority: P2
         Component: c++
        AssignedTo: unassigned@sourceware.org
        ReportedBy: tromey@redhat.com
    Classification: Unclassified


This code is valid c++:

double f(double x) { return x; }
int f(int x) { return x; }

int overload(int x, int (*f)(int)) { return f(x); }

int main()
{
  return overload(0, f);
}


However, gdb does not handle this:

(gdb) p overload(0,f)
Cannot resolve function overload to any overloaded instance

Note that the order of the definitions of "f" matters.
If you change them, this will appear to work, because
gdb will then pick the correct "f" by accident.
