segmentation fault under mod_perl+XML::XPath

["Ruslan U. Zakirov" <cu...@miee.ru>]

	Hello.
I've tried to use XML::XPath under mod_perl 1.27 and Apache 1.3.27, but
got segmentation fault with this peace of code:
use XML::XPath;

my $mfname='/proj/optolink/html/.meta.xml';
my $xp = XML::XPath->new(filename => $mfname);
my $ns = $xp->find('//document[@default="yes"]');
________________________________________
Perl 5.8.0, Apache - with so, unique_id, no expat
mod_perl with everything as DSO
----------------------------------------
Under command line it's working fine and all tests during installation of
XML::XPath were fine, but the same code crush apache+mod_perl.
Backtrace:
