Comment (by chris.cooper@…):

 One solution: change the end of test_all() to look like this:


 {{{
         test_incrementable( x1, x2 );
         test_decrementable( x1, x2 );

         // Make sure the right-hand operator to the shift operator is not
 out-of-range.
         if (true_value(y1) < 0)
             y1 = Y1(-true_value(y1));
         unsigned long m1 = sizeof(true_value(x1)) * 8 - 1;
         if (true_value(y1) > m1)
             y1 = Y1(true_value(y1) & m1);

         if (y2 < 0)
             y2 = -y2;
         unsigned long m2 = sizeof(true_value(x2)) * 8 - 1;
         if (y2 > m2)
             y2 = y2 & m2;

         test_left_shiftable( x1, y1, x2, y2 );
         test_right_shiftable( x1, y1, x2, y2 );
 }}}
