No, this program is absolute correct. Modular types do not overflow,
they use modular arithmetic.
with Ada.Text_IO;
use Ada.Text_IO;
procedure test271 is
type Six_Bits is mod 2**6;
X: constant Six_Bits := 31;
Z: constant Integer := 31;
begin
for J in 0..5 loop
Put_Line (Integer 'Image (J) &
Six_Bits'Image (X * 2**J) &
Integer 'Image ((X * 2**J) mod Six_Bit'Modulus));
end loop;
end test271;
