             Bug #: 13356
           Summary: Be less strict about C++ overloading when calling
                    functions from the inferior
           Product: gdb
           Version: HEAD
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: gdb
        AssignedTo: unassigned@sourceware.org
        ReportedBy: rguenth@gcc.gnu.org
    Classification: Unclassified


When debugging the C++ app

void foo (int *p) {}
int main() {}

gdb does not accept a constant as address

Temporary breakpoint 1, main () at t.C:2
2       int main() {}
(gdb) call foo(1)
Cannot resolve function foo to any overloaded instance

even though there is only a single possible overload candidate.

it's annoying to figure out and paste a cast to whatever specific
pointer type is required here when pasting an address from some
location.

gdb should be more forgiving than a C++ compiler here and do what I want.

Happens a lot to me when debugging gcc built with a C++ compiler.
