I'm not so reluctant. It's a compiler bug.
The following program produces incorrect results on GNAT, or at least
on the version I'm using:
with Ada.Text_IO;
procedure test271 is
type Six_Bits is mod 2**6;
package Six_Bit_IO is new Ada.Text_IO.Modular_IO(Six_Bits);
X : Six_Bits := 31;
begin
for J in 0..5 loop
Ada.Text_IO.Put ("When J=" & Integer'image(J));
Ada.Text_IO.Put (", X*2**J =");
Six_Bit_IO.Put(X*2**J);
Ada.Text_IO.New_Line;
end loop;
end test271;
