(Debian bug #339356, which I realize was never forwarded upstream until now)

procedure gnat_bug is

   type voie is range 1..10;

   protected carrefour is
      entry entree_carrefour (voie);
   end carrefour;

   protected body carrefour is
      entry entree_carrefour (for v in voie)
      when true is
      begin
         accept entree_carrefour(v); -- remove this and you have a valid
program
      end entree_carrefour;
   end carrefour;

begin
   null;
end gnat_bug;

$ gnatmake gnat_bug.adb
