Subject: You are correct...

Go up one level in this thread

I ran the test and you are absolutely correct.  32 bit pawn hash keys
are not usable.  I am not sure when I went to this, but I did look back
thru my test results in my file at the office, and the last time I did any
hash sanity testing was when I did use 64 bits.  Since I made the change to
32 I apparently didn't test well enough.

It is a trivial change to fix, and Crafty is now back to 64 bit signatures.

Glad you took the time to test and kept the idea "alive".  You were
certainly correct about the number of collisions...  and it has to be
unacceptable.
