Hi
I finally had a chance to look at this – looks like there’s a long-standing bug
in PdfParser::ReadXRefStreamContents
Once called, the method assumes that all cross reference information found by
following the “Prev” keys is stored as cross ref streams (XRefStm). The IRS
test documents uses a mix of old style cross-ref tables (xref) and cross ref
streams (XRefStm) in the Prev chain. I’m guessing they’ve been through a couple
of different PDF editors.
PdfTokenizer::GetNextNumber() is throwing an error because the next token is
“xref” instead of number when it reads an xref table it assumes is an XRefStm
Given that fixing this might uncover more problems, and it’s very close to
release day, I’d suggest keeping r1648 for the moment and I’ll submit a patch
after the release.
Does that sound ok?
Cheers
Mark

Hi,
thanks for a quick testing. I committed the patch as r1648 [1]. If
you'll find time and give it more thorough testing by Friday, then
it'll be great (you know, just in case it has any side-effects).
Thanks again and bye,
zyx

Hello,
r1648 works fine for me, for both my quick parser test and for my full suite
of unit tests for my own project. Thank you!
