It fails on amd64 and probably other 64 bit architectures because
adventure's crc code does some bit banging that makes assumptions about
data type sizes. In particular, it assumes that a long is 32 bits wide,
here:

                        if (!(i = crcval >> 24 ^ *p)) {

The right value for a 64 bit arch would be, I think, 56. (And with that
change the crash is vanquished on amd64.) John, the attached patch seems
to work, but bit banging is not exactly my specialty, and I'm not sure
if it will generate the same crcs on 64 bit systems as would be
generated on 32 bit.
