I can add that if it is a bug Crafty18.08 has even a bigger bug
Crafty18.08 cannot see Kf6 in more than 26 minutes
It considers Kd4 for a long time.
Crafty like tiger has a bad order of moves.
Every human is going to check first king goes backward because going forward is
asking for mate but for some reason the order of moves of chess programs start
with king goes forward.
