Guido Jäkel commented on XERCESC-1809:
--------------------------------------
Dear Boris,
for completeness, i let build the Xerces-C samples, too. As expected, now they
are roughly running.
To compare with the above, here the current strace of SAX2Count.

> Key: XERCESC-1809
> URL: https://issues.apache.org/jira/browse/XERCESC-1809
> Project: Xerces-C++
> Issue Type: Bug
> Affects Versions: 2.8.0
> Environment: Gentoo-Linux (emerge --version -> Portage 2.1.4.4
> (default-linux/amd64/2007.0, gcc-4.1.2, glibc-2.6.1-r0, 2.6.21-gentoo-r4

> I try to advance the Gentoo ebuild for dbxml to 2.4.13. For that, Xerces-C
> 2.8.0 and XQuilla is a prerequesite. The Gentoo ebuild for Xerces-C have been
> tweeked to include the patches for XQilla this days. Now i'm able to build
> dbxml on 32bit and 64bit. On 32bit it seems to work from the first tests, but
> on 64bit even a simple "dbxml -v" dies with an segmentation fault.
