嘗試更改24位位圖的RGBQUAD時出錯

我在MFC中使用Visual Studio 6.0製作了一個應用程序，其中我正在更改位圖的顏色深度，該應用程序適用於除24位位圖以外的所有位圖圖片。我無法弄清楚它爲什麼會給出錯誤。我知道它發生錯誤的地方。這是代碼。嘗試更改24位位圖的RGBQUAD時出錯

void CbitmapView::OnMenuRedMode() 
{ 
CBmpViewerDoc* pDoc = GetDocument(); 
ASSERT_VALID(pDoc); 
if(pDoc->m_bColorModeFlag == TRUE){ 

#ifdef _DEBUG 
    CMemoryState oldState,newState,diffState; 
    oldState.Checkpoint(); 
#endif 
m_bmiView = (BITMAPINFO *)malloc(pDoc->dwInfoSize); 
//m_bmiView = (BITMAPINFO *)GlobalAlloc(GPTR,pDoc->dwInfoSize); 
CopyMemory(m_bmiView,pDoc->m_bitmapinfo,pDoc->dwInfoSize); 
// m_bmiView = pDoc->m_bitmapinfo; 
int nColorUsed = m_bmiView->bmiHeader.biClrUsed ; 
if(nColorUsed != 0){ 
    for(int i = 0; i < nColorUsed ; i++){ 
     m_bmiView->bmiColors[i].rgbRed = (BYTE)255; 
    } 
}else if(nColorUsed == 0){ 
    nColorUsed = (1 << pDoc->m_bitmapinfo->bmiHeader.biClrUsed); 
    for(int i = 0; i < nColorUsed ; i++){ 

     m_bmiView->bmiColors[i].rgbRed = (BYTE)255; 
    } 
} 

pDoc->m_bmpHandle = CreateDIBSection(NULL, m_bmiView,DIB_RGB_COLORS, 
    (void **)&pBitsView, NULL, 0); 

CopyMemory(pBitsView,pDoc->m_pBits,pDoc->dwBitsSize); 
if(m_bmiView != NULL){ 
    //GlobalFree(m_bmiView); 
    free(m_bmiView); *//error comes at this point when it is 24 bitmap image.* 
    //delete(m_bmiView); 
} 

#ifdef _DEBUG 
newState.Checkpoint(); 
if(diffState.Difference(oldState,newState)){ 
    MessageBox(_T("Memory leak detected")); 
    diffState.DumpAllObjectsSince(); 
} 
#endif 

Invalidate(); 
// TODO: Add your command handler code here 
}

}

的erorr是由VS6.0

損傷所示如下：在正常0x00423DF0塊（＃234）之後。
