Subject: Crafty bug?

Author: James B. Shearer

      I was playing a Crafty clone on ICC and the following position arose:

setboard r5k1/ppp1Q2p/1q4p1/8/8/2P1B3/bP4P1/4R1K1 b - - 0 24

The clone played qb6xb2 which loses quickly after be3-d4.  I checked the
position after the game was over with crafty 15.15 on my k6-233.  Crafty seems
to take an inordinate amount of time to reject qxb2 (over 100 seconds).  Every
other program I have (cm5500, rebel8, rebel decade20, fritz4) either never
considers qxb2 or rejects it quickly (under 1 second).  Is this a bug?
