Qt SIGSEGV

        m_bThreadFlag = true;

    if(NULL != m_pNtripSocket){

        delete m_pNtripSocket;

        m_pNtripSocket = NULL;

    }

    if(NULL == m_pNtripSocket){

        m_pNtripSocket = new ProcessVibConnect(this);

        connect(m_pNtripSocket, SIGNAL(proDataReceivedNtrip(char*, int)),this, SLOT(OnDataReceivedFromNtrip(char*, int)),Qt::DirectConnection);

执行到 delete m_pNtripSocket; 就崩溃，提示 ：
 原来是 没有给指针初始化NULL  引起的。。。。。。。。。。。。。。
