show that the app is calling mfc42.275 -- the MFC CArchiveStream constructor. 
CArchiveStream::Stat apparently just returns OLE_E_ADVF

I took a look at OLEPictureImpl_Load, and it seems that we should check the
return value from Stat (and also from HeapAlloc) and use other ways to find out
how much memory to allocate.
