Including checks for dangling pointers??
What should this print?
with Ada.Text_IO;
procedure Dangling_Pointer is
type Int_Access is access all integer;
Save : Int_Access;
type AirSpeed is record
Altitude : aliased integer := 9;
end record;
type AoA (Rudder: access AirSpeed) is limited null record;
function WoW (Slats: access AirSpeed) return Int_Access is
begin
return Slats.Altitude'Access;
end;
procedure Calculate is
Fuel: aliased AirSpeed;
Heading: AoA (Fuel'Access);
begin
Save := WoW (Heading.Rudder);
Ada.Text_IO.Put_Line (integer'image(Save.all));
end Calculate;
procedure Mess_with_stack is
Dummy: array(1..10) of integer := (others => 17);
begin
null;
end Mess_with_stack;
begin
Calculate;
Mess_with_stack;
Ada.Text_IO.Put_Line (integer'image(Save.all));
end Dangling_Pointer;
