I told you that these problems are very hard to debug.

What do you mean with "I can build the package with -j1"? Do you mean that the 
error does not happen when you build with -j1?

Unfortunately, there is not useful error message.

Looks good.

Okay, what version of the expat are you using?

It works here with libexpat-devel-2.0.1.

Ah, I saw in the installation log that it called 
/tmp/go-openoffice/trunk/src/ooo-build-3.2.0.10/build/ooo320-m12/solver/320/unxlngx6.pro/bin/regcomp
dirrectly

Okay, please do the following:

regcomp_wrapper=/tmp/go-openoffice/trunk/src/ooo-build-3.2.0.10/build/ooo320-m12/solver/320/unxlngx6.pro/bin/regcomp
rm $regcomp_wrapper
cp regcomp.patched $regcomp_wrapper
chmod 755 $regcomp_wrapper

and try to run the installer.

IMPORTANT: it is important to remove the old regcomp file before you install 
the new one. Otherwise you would rewrite the real binary regcomp.bin (it is a 
hardlink or so)

You might get the strace log from my build at
http://download.go-oo.org/tstnvl/LuceneHelpWrapper-registration/strace.1.log.bz2

Let's check the strace log first.

BTW: What is the purpose of your build? Are you the official OOo package 
maintainer for the ArchLinux distro?
