I was wondering how to initialize the constant Null_Azerty in the
following piece of code :

-------------------------------------
with Ada.Strings.Unbounded;

package Ess is

   use Ada.Strings.Unbounded;

   type Azerty is private;

   Null_Azerty : constant Azerty;

private

   type Azerty is new Unbounded_String;

   Null_Azerty : constant Azerty := ... ;

   --  I tried this with GNAT and it doesn't works ?
   --  Is it a bug ?
   --Null_Azerty : constant Azerty := Azerty (To_Unbounded_String
(""));

   --NA : Unbounded_String := Null_Unbounded_String;
   --Null_Azerty : constant Azerty := NA;

end Ess;
-----------------------------------

If it's a GNAT bug let me know and I'll report it.

Thanks for your help,
Pascal.
