I think 32 bits is too small to hash pawn configurations.

I use 64 bits, but store only the lower 32 bits in the hash table (key) and use
the upper 32 bits to form the index.  Seems to work fine for me, but I think Bob
may have said even this approach is risky (?).

Of course you only need to do the above to squeeze more into 32 bytes of hash
record, if this is important to you.
