I joined this list recently, to see whether the Poppler versions
of the  Xpdf  utilities worked any differently from the non-Poppler

I'm working on a Mac, with MacOS X v10.4.11, and have successfully
built the utilities from this latest release.

All of  pdfinfo, pdffonts, pdftohtml, pdftotext, pdftops, pdftoppm
and  pdfimages  work fine on a simple 1-page PDF that I created
with pdfTeX.

However, all of these fail with a  "Bus error" on more
complicated multi-page PDFs, which you can find here:


I'm particularly interested in  pdffonts, pdftohtml, pdftotext
as I want a free tool to be able to correctly extract the text
from documents such as the above PDFs.

They must extract the *complete* textual contents, using the
  CMap font-encoding resources that these PDFs contain.

Non-poppler versions of the utilities;  e.g.

   rossmoor% pdftotext -v
   pdftotext version 3.02
   Copyright 1996-2007 Glyph & Cog, LLC

work to some extent, but certainly not completely.
  (pdfimages  works but the output is incomplete and useless
   and  pdftoppm  also gives a  Bus error .)

For example, this is part of the text extracted from  5019-e-mmap.pdf
using  pdftotext (v3.02)

   Figure 1: The Moebius strip. Consider the two-sheeted covering
    \pi  : \BbbS 2 \rightar P and the inverse image \pi   - 1 (L)
   of one of these circles.

It's pretty good, except that \rightarrow  has been truncated
to 8 characters.  There are many similar instances within the
full text.  However, the Poppler version doesn't get far enough
through the document to see this --- at least not for me.

BTW, the text selection in Adobe Reader (versions 7.* & 8.*)
does extract the text more completely; so there is either
a bug or a design flaw within the  pdftotext  utility.

Hope this helps,
and that you can help me.
