Hi Peter, The segfault did occur with the latest XeTeX version 0.9997.4. Updating from 0.9997.3 to 0.9997.4 changed it from segfaulting immediately when loading unciode-math to segfaulting only in certain situation, depending on what kind of formulas you typeset. with fontconfig-2.7.3 (libfontconfig.so.1.4.3). Ubuntu 10.4 ships with fontconfig-2.8 rather than fontconfig-2.7.x. Could there be compatibility issues with that? Would it be better to use a static version of libfontconfig? Regards, Ulrik P.S: As I wrote earlier, my self-compiled version did not segfault when compiled on Ubuntu 10.4, but it did not work correctly either. As for the latter, I suspect another issue which may be unrelated to the segfaults. - Original Nachricht Von: Peter Breitenlohner p...@mppmu.mpg.de An: Karl Berry k...@freefriends.org Datum: 19.07.2010 11:23 Betreff: Re: [tex-live] [XeTeX] TeXLive Pretest - XeTeX segfaults on LInux 64 On Fri, 16 Jul 2010, Karl Berry wrote: What is the build environment for the x86_64-linux texlive binaries?

Only stuff like fontconfig or zlib was dynamically linked. I am running Ubuntu 10.4 on AMD 64, but I haven't checked yet which libaries are provided as 64 bit versions. I wouldn't assume that the problem is with dynamic linking per se. I rather suspect that there are some issues with parsing the font information on 64 bit systems in general. It doesn't always produce segfaults, but it may simply produce incorrect results. When I first reported it to the XeTeX list some weeks ago, my problem was confirmed to exists on Solaris 64 as well, so this seems to be a generic problem of 64 bit architectures. I'm pretty sure this is true; it's probably a straightforward error related to data structures/sizes/etc in the code that interprets the font tables, but I haven't had the opportunity to set up a 64-bit system and try to debug it. If someone on a 64-bit system cares to do a debug build and provide a backtrace from such a crash, that would be a good start towards identifying the problem.

I always install both because some legacy tools do not work without i386 libraries.

Anyone who has been experiencing this problem is welcome to build and test the new version to confirm that the crash no longer occurs; obviously, I have not been able to test it personally on all possible systems and configurations.

\setromanfont{XITS}

For the future: it is much easier to debug problems (any problems) if
they can be reproduced using fonts that are included in TL. Installing
system fonts is not easy, versions are likely to be different, etc.
At any rate, hoping that Jonathan's fix will suffice to at least avoid
the crash, I've asked the TL folks to rebuild.
Thanks to you and Jonathan and Thanh :).
