Ok perfect thanks.

No matter what, I can't trigger this segfault.

Do you have a build log for the package? and could you send me the
make/defines.mk in the build tree?

gcc versions and usual tool chain info.. maybe it's a gcc bug or maybe
it's an optimization that behaves differently between debian and fedora.

I have attached a small test case to simply test libccs. At this point I
don't believe it's a problem in libfence. Could you please run it for me
and send me the output? If the bug is in libccs this would start
isolating it.

[root at fedora-rh-node4 ~]# gcc -Wall -o testccs main.c -lccs
[root at fedora-rh-node4 ~]# ./testccs 
-hopefully some output-

and please check the XPath query at the top of main.c as it could be
slightly different given your config.

Thanks
Fabio
