> The number of bits from bit #m to #n is n - m plus 1.

> -#define MIDDLE_BITS(k, m, n) LAST_BITS((k) >> (m), ((n) - (m)))
> +#define MIDDLE_BITS(k, m, n) LAST_BITS((k) >> (m), ((n) - (m) + 1))

I cannot comment on this patch but if this fixes a sample
of yours, please add a fate test.

Thank you, Carl Eugen
