The checkasm was just written to just to trigger all the theoretical
edgecases. I know there is a decent range of values which pass the d0 +
d3 < beta check and overflow in (9 * (q0 - p0) - 3 * (q1 - p1) + 8) for
int16_t. I'm not 100% sure that these values can be output by the
decoder, and even if so they're rare.
