Here I can reproduce it. 
Seems related to poppler.

Related to poppler? I see it crashing in freetype eh ;-)

Works for me using poppler 0.10.1 and freetype either 2.3.5-1ubuntu4.8.04.1 or compiled from cvs

You're right :-P 
Updating poppler to 0.10.1 didn't solve the issue.

(Regression Crash between freetype 2.3.5 and 2.3.7 / cff_parse_real(), seems to be related to GCC optimizations).

Helge, what freetype2 version do you have?

After recompiling freetype 2.3.7 (after unsetting CFLAGS and CXXFLAGS), I can't reproduce this bug anymore. So it seems to be fault of a GCC optimization on freetype2 2.3.7 :)

# rpm -qa|grep freetype
libfreetype6-2.3.7-1plf2009.0
freetype-1.3.1-29mdv2009.0
freetype-tools-1.3.1-29mdv2009.0
libfreetype6-devel-2.3.7-1plf2009.0

Dario: did you rebuild the package with different options, or do a clean build from upstream sources?

Three Okular bugs, all involving SIGFPE, perhaps all in freetype:
#170427
#176304
#176320

Brad:
My distribution (ArchLinux) uses precompiled binaries (compiled with "-O2 -pipe")
But we can compile ourselves the distribution packages (it uses a BSD-port like system), and thus changing some compile options and so on.
I have compiled freetype2 (2.3.7) from source disabling the GCC options ("unset CFLAGS", seting CFLAGS="-g" ) to check the information I found about this bug (the link in comment 3). Then, I installed my own source-build package to overwrite the original freetype package. And the bug seems to be gone. I could even read the PDF :).
Is that what you were asking for? If not, just ask me again :)

I have only recompiled kdegraphics after updating my poppler packages to 0.10.1. But this wasn't neccesary to do after updating my freetype2 package.

Dario: I was trying to figure out whether it could be caused by some patches applied to freetype (Ubuntu / Debian has 107K diff applied, most of which looks harmless, but I didn't do a full check), or whether it is more likely a compiler problem. Sounds like the compiler optimisations might be the issue.

What gcc version is this with?

Here: I'm using gcc (GCC) 4.3.2

Albert, Brad: is this problem strictly freetype's, or how it is used within poppler?

Created attachment 30419 [details]
Okular crash file

This is the crash report I got when trying to browse a PFD file with okular.

This is an old crash in the Poppler library (that has nothing to do with this bug report); please update your Poppler.

Strictly freetype as far as i know.

As seen in various comments, this bug belongs either to freetype, or to gcc itself.
Thus closing it as UPSTREAM.
