CHeaderCtrl is abnormal when release compilation.

I save one integer value in Column of ListCtrl via "SetItem";
But I can't get the value via "GetItem" if the application is complied using "Release" configuration.

my test environment is vs2010 and vs2008.

the sample code is below:
===========================================
// m_ListCtrl is CListViewCtrl object.
    m_ListCtrl.SubclassWindow(::GetDlgItem(m_hWnd, IDC_LIST1));
    CHeaderCtrl header = m_ListCtrl.GetHeaderCtrl();
    m_ListCtrl.InsertColumn(0, _T("Hello"), 0, 80);
    HDITEM hd = {0};
    int tt = 50;
    BOOL ret;
    hd.mask = HDI_FILTER;
    hd.type = HDFT_ISNUMBER;
    hd.pvFilter = &tt;
    ret = header.SetItem(0, &hd);
    if (ret != TRUE)
    {
        ::MessageBox(m_hWnd, _T("wrong1"), NULL, 0);
    }
    HDITEM hh = {0};
    int ss = 0;
    hh.mask = HDI_FILTER;
    hh.type = HDFT_ISNUMBER;
    hh.pvFilter = &ss;
    ret= header.GetItem(0, &hh); // return FALSE when release.
    if (ret != TRUE)
    {
        ::MessageBox(m_hWnd, _T("wrong2"), NULL, 0);
    }
    if (ss != tt)
    {
        ::MessageBox(m_hWnd, _T("wrong3"), NULL, 0);
    }
