又一个总线错误

void ha_process_pkttimer(void *data)
{
ha_packet_t *packet;
ha_packet_ctrl_t *controller;

if (data == NULL)
return;

packet = data;   没有将void *转换为(ha_packet_t *)
controller = packet->controller;

if (controller->check_func(packet) && controller->timeout_func != NULL) {

}

注意红色部分，导致在 if (controller->check_func这句时引起总线错误
