Hello,

I have a problem with some code I've written. The compiler (GNAT 3.15p
on Windows) reports an error whereas I think it should not.


Package spec:

package Pkg is
  procedure Proc (Host : STRING; RC : out Integer; Identifier : in
Integer := 0);

  procedure Proc (Host : STRING;
                 Time_Response : out Integer; RC : out Integer;
                 Time_Wait : Integer := 1000;
                 Identifier : Integer := 0);
end Pkg;


Main program:

with Text_IO;
with Ada.Command_Line;  use Ada.Command_Line;

with Pkg; use Pkg;

procedure PkgTest is
  RC : Integer;
begin
  if Argument_Count /= 1
  then
    Text_IO.Put_Line ("call: PkgTest <ip>");
    return;
  end if;
  
  Proc (Argument (1), RC, 2507);
  Text_IO.Put_Line ("RC=" & Integer'Image (RC));
end PkgTest;


The compiler says, that the procedure call is ambigous, but I think, it
is clear, that "Proc" from line 2 should be used, as it has parameters
(in, out, in) while "Proc" from line 4 has (in, out, out). And the value
(2507) in the call of "Proc" can not be used as an "out" parameter. It
this a know error, or do I have strong misunderstandings there?

pkgtest.adb:15:03: ambiguous expression (cannot resolve "Proc")
pkgtest.adb:15:03: possible interpretation at pkg.ads:4
pkgtest.adb:15:03: possible interpretation at pkg.ads:2
