If you were using 64 or 32 bit and are trying to use the other, that
will make a difference for the hash seed.  The hash seed is the seed +
the architecture (32 or 64 bits).  This is because hash values are
numbers that are one word, so on 32-bit computers, hash values can be
up to 2**32 (or maybe 2**31, I'm not sure), but on 64-bit computers,
it's 2**64 (or 2**63).

That test report says 64-bit, so you need to make sure you are using that again.
