这是crafty程序中一段源程序：

void _init() {

   int delta;

   int x, y;

   int dist, tmp;

   // Distance[]

   for (delta = 0; delta < DeltaNb; delta++) Distance[delta] = -1;

   for (y = -8; y <= +8; y++) {

      for (x = -9; x <= +9; x++) {

         delta = y * 16 + x;

         assert(delta_is_ok(delta));

         dist = 0;

         tmp = x;

         if (tmp < 0) tmp = -tmp;

         if (tmp > dist) dist = tmp;

         tmp = y;

         if (tmp < 0) tmp = -tmp;

         if (tmp > dist) dist = tmp;

         Distance[DeltaOffset+delta] = dist;

      }

   }

}

这段程序有个致命错误.

与assert(delta is ok(delta))相互矛盾.把ollydebug调试器设置成即时加载后，程序在运行中断后便自动停在

for (y = -8; y <= +8; y++) {

这一行....
