Hmm...  are you sure?


program project1;

{$mode objfpc}{$H+}


procedure print(num: Integer);
begin
  writeln(num);
end;

procedure foo(cnt: Integer {-4});
var
  x : integer = 0;    {-8}
  y : integer;        {-12}
begin
  print(x);
  print(y);
  inc(x);
  inc(y);
  if cnt < 5 then begin
    foo(cnt + 1);
  end;
end;

begin
  foo(0);
end.
