*size_out = sizeof(STU_PACK_HEAD)+pHead->body_len+2;
uint16_t crc = crc16_modbus(out,*size_out-2);
printf("size_out=%d \n",*size_out);
uint16_t *pcrc = (uint16_t*)(out+sizeof(STU_PACK_HEAD)+pHead->body_len);
printf("pcrc addr=0x%08lx 0x%08lx \n",(UINT32)pcrc,(UINT32)(out+sizeof(STU_PACK_HEAD)+pHead->body_len));
//*pcrc = crc; /// 使用这一句就死机了，换成下面两句正常
//*(uint16_t*)(out+sizeof(STU_PACK_HEAD)+pHead->body_len) = crc;//crc16_modbus(out,*size_out-2);
*(out+sizeof(STU_PACK_HEAD)+pHead->body_len) = (crc&0x00FF);
*(out+sizeof(STU_PACK_HEAD)+pHead->body_len+1) = (crc&0xFF00)>>8;
我想知道为什么用 *pcrc = crc ; 这样就死掉了
