GDI：CreateDIBSection / CreateDIBitmap几个小时后失败

Question

我在Windows 7上使用GDI / MFC开发了一个Deskstop应用。

此应用每5秒加载一张图片。 4-5小时后崩溃，我在CreateDIBSection中收到了ERROR_INVALID_PARAMETER。

这是我的代码：

UINT local_colors = 2;

RGBQUAD image_colormap[2];

image_colormap[0].rgbRed = image_colormap[0].rgbGreen = image_colormap[0].rgbBlue = 0;

image_colormap[1].rgbRed = image_colormap[1].rgbGreen = image_colormap[1].rgbBlue = 255;

UINT local_bmpInfo_size = sizeof(BITMAPINFO) + local_colors * sizeof(RGBQUAD);;

LPBITMAPINFO local_bmpInfo = (LPBITMAPINFO ) malloc(local_bmpInfo_size);

local_bmpInfo->bmiHeader.biSize        = sizeof(BITMAPINFOHEADER);
local_bmpInfo->bmiHeader.biBitCount    = 1;
local_bmpInfo->bmiHeader.biClrUsed     = local_colors;
local_bmpInfo->bmiHeader.biCompression = BI_RGB;
local_bmpInfo->bmiHeader.biHeight      = 320l;
local_bmpInfo->bmiHeader.biPlanes      = 1;
local_bmpInfo->bmiHeader.biWidth       = 320l;
CopyMemory(local_bmpInfo->bmiColors, image_colormap, local_colors* sizeof(RGBQUAD));

HDC local_hDC = ::GetDC(NULL);

if(local_hDC)

{

UCHAR* image_bits = NULL;

HBITMAP local_imgHandle = CreateDIBSection(local_hDC , local_bmpInfo, DIB_RGB_COLORS, (void**)&image_bits, NULL, 0l);

}

::Release(NULL,local_hDC);

你有什么主意吗？
