The conclusion is that this is a random result. If you play crafty vs the commercial programs, which are tactically stronger than most 'freeware' programs, crafty will find itself in more 'trouble'. And _that_ will make the ponder=off problem I have explained show up. If it doesn't get into any trouble in most games, this problem won't show up.
