Hi, I noticed in the latest pdftex-1.20c-beta-20050121 is a patch that I made to the file FoFiType1.cc which corrects a seg-fault in pdftex that occurs when including a document with the Mathematica fonts. It is probably preferable to instead use the patch from the pdf maintainer, which should be included with this email. If you have already made this change, then please disregard my email. Thanks, Martin Otte Begin forwarded message:

Subject: pdflatex segmentation fault and patch to fix From: "Martin Otte" Date: Tue, January 11, 2005 23:40 To: gerben.wierda@rna.nl

Hi,

Thanks for your excellent packaging of tex/latex for the mac.

I am using the TeX Live 2004 and teTeX 3 distribution from the tex i-package released on 2004/12/01.

With this i-package, pdflatex always seg-faults for me when I include pdf figures generated using the PStill postscript-to-pdf converter. These pdfs open fine with Acrobat and Preview. I downloaded the final TeX Live 2004 source package, compiled pdfetex, ran the executable under a debugger and found that pdflatex crashes in the xpdf library. I then verified that these pdf's also crash the xpdf viewer on my linux machine.

The crash occurs in the file libs/xpdf/fofi/FoFiType1.cc. There is a string buffer size variable "n" that becomes negative and causes the program to crash. I attached a patch that can be used from the libs directory of the TeX Live distribution that prevents the buffer size from becoming negative.

That's a known bug in Xpdf 3.00. I'm attaching a patch file which should fix it.
