量化交易ctp，在断开行情连接服务（api->release时）程序崩溃了

Question

我在本机虚拟机断开行情连接完全没有问题，但放到其他的服务器上断开时就崩溃了

if (this->md_user_api != nullptr)
{
      LOG_INFO("断开行情服务");
      this->connect_status = false;
      this->login_status = false;
      //this->md_user_api->RegisterSpi(NULL);
      this->md_user_api->Release();
      this->md_user_api = NULL;
}
