线程调试死机

static DWORD WINAPI ListenThread(void* pv)
{
    XMsmq * pMsmq =(XMsmq *)pv;
    CString strMsg;
    pMsmq->GetMsg(strMsg);
    while (1)
    {         
         HANDLE eventMsmq = pMsmq->GetEventHandle();
        if (WaitForSingleObject(eventMsmq, INFINITE) == WAIT_OBJECT_0)
        {           
            CString strMsg;
            pMsmq->GetMsg(strMsg,TRUE);
            pMsmq->m_fnCallBack("bb","sdf");        
        }                   
    }
    return 0;
}
BOOL XMsmq::AsyncReceive(MQRECEIVECALLBACK fnReceiveCallBack)
{
    if(m_hQue == NULL) return FALSE;
    m_fnCallBack = fnReceiveCallBack;
    DWORD dwThreadID;
    m_hThreadHandle = CreateThread(NULL, 0, &ListenThread,
            this, 0, &dwThreadID);
    return TRUE;
}

在线程函数外设置断点 ，并且也再线程设置断点则频繁出现死机。由于vc调试器问题，只在线程函数内或者外部设置断点则不会出现死机
