Questiondeque problem. Does this code has any problem? [solved] Pin

C#
{
    CTempLock tempLock(&m_FrameListLock);
    if (m_FrameQueue.size() == 0)  return 0L;

    pFrameData = m_FrameQueue.front();
    m_FrameQueue.pop_front();
}

if (WaitForSingleObject(this->m_hCloseEvent, 0) == WAIT_OBJECT_0)
{
    return ZMD_OK;
}

try
{
    if (pFrameData != NULL)
    {
        if (pFrameData->lpData != NULL)
        {
            try
            {
                this->DistributeFrame(pFrameData->lpData, pFrameData->iSize);
                byte*  pBuf = reinterpret_cast<byte*>(pFrameData->lpData);
                delete[] pBuf;
            }
            catch (CException* e)
            {
                e->Delete();
            }
        }
        delete pFrameData;
        pFrameData = NULL;
    }
}
catch (CException* e)
{
    e->Delete();
}

}



XML
There is a error that happens in the following code.
byte*  pBuf = reinterpret_cast<byte*>(pFrameData->lpData);
<b>delete[] pBuf;</b>

Just as the image, here.
https://www.dropbox.com/s/ckqkz88qnifus4g/Error.png
I find that the pFrameData->lpData is a wild buffer point.  I do not know when the buffer is released?  Or this deque has some problem?


The class is here.

XML
class CStreamProcess
{
    HRESULT ProcessFrames();

    void DistributeFrame(const LPVOID const lpBuf, int  dwSize);

    HANDLE  m_hCloseEvent;
    HANDLE  m_hFrameProcessEvent;
    std::deque<SZMDFrameData>   m_FrameQueue;
    CCriticalSection    m_FrameListLock;
};


--------------------
I have resolved this problem. Its a mistake of using CCriticalSection.
