Yes, that's what I thought too.  How about this:

with Ada.Text_Io, Ada.Unchecked_Deallocation;
procedure Vararray is
   type Var_Array is array(Positive range <>) of Integer;
   type Var_Array_Access is access Var_Array;
   Size : Positive;
   Variable : Var_Array_Access;
   procedure Free is new
     Ada.Unchecked_Deallocation(Var_Array, Var_Array_Access);
begin
   Size := 50;
   Variable := new Var_Array(1..Size);
   for I in Variable'Range loop
      Variable(I) := I;
      Ada.Text_Io.Put_Line("var_array(" & Integer'Image(I) & ") = " &
                           Integer'Image(I));
   end loop;
   Free(Variable);

   Size := 80;
   Variable := new Var_Array(1..Size);
   for I in Variable'Range loop
      variable(I) := I;
      Ada.Text_Io.Put_Line("var_array(" & Integer'Image(I) & ") = " &
                           Integer'Image(I));
   end loop;
   Free(Variable);
end Vararray;
