Il me semble que ce n'est pas practique :

pragma Restrictions (No_Allocators);

with Ada.Numerics.Generic_Real_Arrays;

package Globals is
   pragma Preelaborate (Globals);
   type T is digits 6;
   package Linalg is new
     Ada.Numerics.Generic_Real_Arrays (T);

   subtype Carré is
     Linalg.Real_Matrix (1 .. 20_000, 1 .. 20_000);

   M1, M2, Résultat : Carré;
end Globals;

with Globals;

procedure Run_Using_Globals is
   use Globals;
   use type Carré;
begin
   Résultat := M1 * M2;  -- "*" de la bibliothèque
end Run_Using_Globals;


$ ~/News/run_using_globals 

raised STORAGE_ERROR : stack overflow
$

(Aucune réponse après de compiler avec -O.)


Alors, si on veut déclarer des objets, euh, grands,
et si le compilateur est GNAT, il faut être attentif !
