The memory is fading, I haven't been too successful myself, sorry.
However, I have noted (or at least I think I have) that nested
packges have resulted in compilation times in excess of what the
the same packages as child packages require (the packages contain
a few instantiations of Charles containers).

Another source of long compilation time is displayed in

   procedure PT is
      X : constant := 1.0 + 2.0 ** (-1000000);
      Y : constant := 1.0 + 2.0 ** (-1000001);
      Z : constant := 2.0 ** (1000001) * (X - Y);
   begin
      Put_Line (Float'Image (Z));
   end PT;
