TOC in header: PDF output wrong



we have a customer who embedded the TOC inside the header of the first page. This generates a wrong output when rendering to PDF. I was able to reduce the problem to our code, which updates the page numbers for toc fields.

            var lic = new License();

            var doc = new Document(@"S:\tmp\test.docx");

            // Inhaltsverzeichnis
            foreach (var fs in doc.GetChildNodes(NodeType.FieldStart, true).AsEnumerable().Cast<FieldStart>()
                .Where(fs => fs.FieldType == FieldType.FieldTOC))


Attached files:
test.docx -> reduced input file
out.docx -> above code saved to docx (output still is good)
out.pdf -> above code saved to PDF (output is wrong)
word.pdf -> PDF generated with word (from test.docx)

If you remove the loop, updating page numbers, the PDF generated with Aspose looks fine btw. (1.1 MB)

Kind Regards,
