I am cross costing a question from SO since it looks like all the Ada experts are here and not there :)

https://stackoverflow.com/questions/48939845/non-local-pointer-cannot-point-to-local-object


Can someone explain why I get "non-local pointer cannot point to local object" error, even though it looks like "Arr" and "Arr_Access" have the same accessibility level?

Can I overcome the problem without dynamically allocating memory and without using "Unchecked_Access"?


with Interfaces.C;
with Interfaces.C.Strings;

procedure X is

   type Integer_Access is access all Integer;

   Arr_Access : Interfaces.C.Strings.char_array_access;
   Arr : aliased Interfaces.C.char_array := Interfaces.C.To_C ("From");

   A : Integer_Access;
   I : aliased Integer := 6;

begin

   Arr_Access := Arr'Access;
   A := I'Access;

end X;



Thank you,
Artium
