Crafty might have a hash bug, perhaps related to repetition detection.  In the
following position, it plays h5, which it thinks leads to a draw by repetition.
Instead, it loses pretty fast.  I have been able to get it to show the h5 line,
which it sticks to forever with 0.00, but I can't reliably repeat the behavior.
However, if you vary the thinking times of the previous moves, or start with the
position from scratch, it won't repeat the erroneous line.

5q1k/3Q2b1/7p/8/3pBP2/2p3PP/4K3/8 b - - 0 56  h5?
