[XeTeX] [tex-live] TeXLive Pretest - XeTeX segfaults on LInux 64

[ulrik.vieth at arcor.de]

Hi Peter,

I had posted my configuration in an earlier message:
http://tug.org/pipermail/tex-live/2010-July/026654.html

$ xetex --version
XeTeX 3.1415926-2.2-0.9997.4 (TeX Live 2010)
kpathsea version 6.0.0

named COPYING and the XeTeX source.
Primary author of XeTeX: Jonathan Kew.
Compiled with ICU version 4.4 [with modifications for XeTeX]
Compiled with zlib version 1.2.3; using 1.2.3
Compiled with FreeType2 version 2.3.11; using 2.3.11
Compiled with fontconfig version 2.7.3; using 2.8.0
Compiled with libpng version 1.2.40; using 1.2.40
Compiled with xpdf version 3.02pl4

zlib and freetype versions did match on Ubutu 10.4, 
only fontconfig had a version mistmatch.

Regards, Ulrik.
