Exception in Gdiplusbitmap.h

MFC

Hi all,

I have an exception like this:

Here are my code

CPictureControl m_textImage;

m_textImage.Load(data.data1->GetData(), 
data.data1->GetSize());
Bitmap img(m_textImage.m_pStream, TRUE);
			Bitmap* pThumbnail = static_cast<Bitmap*>(img.GetThumbnailImage(85, 95, NULL, NULL));				
			// attach the thumbnail bitmap handle to an CBitmap object
			pThumbnail->GetHBITMAP(NULL, &hBmp);
			pImage = new CBitmap();		 
			pImage->Attach(hBmp);
			cImage->Add(pImage,pImage);
			delete pThumbnail;
			delete pImage;

In my code cImage is CImageList

But when I run, some time error happens at: gdiplusbitmap.h

inline
Image::~Image()
{
    DllExports::GdipDisposeImage(nativeImage);//Error here
}

Error Message is: An unhandled exception of type 'System.AccessViolationException' occurred in Test.exe

Additional information:
Attempted to read or write protected memory. This is often an indication that other memory is corrupt

It happens randomly and not very often. I don't know how to handle it.

Please help me.
Thanks,
