@ms3534 ,
PyPDF4 is no more active whereas PyPDF2 is. I've tried your test file in PyPDF2 and the error is confirmed there too. I will analyze the issue and try to produce a fix ; to do that can you duplicate the issue in https://github.com/py-pdf/PyPDF2 ?

also this code is a minimized test version

from PyPDF2 import PdfFileReader, PdfFileMerger
merger = PdfFileMerger()
merger.append(PdfFileReader(open('C:\file-0.pdf', 'rb')))
