Known problem due to an 'optimisation' added in pdftex at some
point. I have removed it for the win32 version.
// Called when an image has been written and it's resources in
// image_tab are freed. We cannot deallocate the PdfDocument yet, as
// future pages of the same document may be embedded. As an
// optimization, we do delete it if it's a one-page document.
// Akira Kakuto has suggested to make epdf_delete empty, so
PdfDocument *pdf_doc = (PdfDocument *) epdf_doc;
xref = pdf_doc->xref;
if (pdf_doc->doc->getCatalog()->getNumPages() == 1)
Change the '#if 0' to '#if 1' or remove the matchine #if/#endif pair.
