Re: pdftex core dump when including certain pdf files

Hi Andre - as Akira mentioned (thanks Akira), though maybe you didn't
see his reply, including your PDF with the floating-point StemV values
doesn't crash with the pdftex in TeX Live 2016, which is version
3.14159265-2.6-1.40.17, or any version back through 2010,
3.1415926-1.40.11.  I stopped looking there. 

This is with the original pdftex distributed with TeX Live, the
i386-linux binary.  Therefore I surmise this is probably a bug in some
way that Ubuntu (or more likely Debian) has reconfigured/recompiled the
program.  E.g., something in poppler vs TL's "libxpdf".

I suppose it is possible that it is something about i386- vs. x86_64-,
assuming you are on 64-bit, but that seems less likely.

So ... I cc Norbert.  Norbert, does the attached tryplot.tex (which
merely includes the attached plot.pdf) crash with Debian pdftex?  The
crucial thing is the non-integer value of StemV in plot.pdf.  (The
original report leading to the thread here is at
https://sourceforge.net/p/pyx/mailman/message/35118842/, FWIW.  I
simplified the report to use plain TeX instead of LaTeX.)  --karl
