> on
> SERVER_SOFTWARE: Apache/2.0.44 (Win32) mod_perl/1.99_08-dev
> Perl/v5.8.0
and as suggested :
LIBXML2.DLL VERSION 2.4.26
XML::LibXML version 1.52
everything rebuild debug
test code
-----------------------
use testxml(); (in startup.pl)
testxml
---------------------------
package testxml;
use strict;
use warnings;
use XML::LibXML();
my $base='c:/apache2/mason';
our $promod=
XML::LibXML->new->parse_string("<?xml version=\"1.0\"?
><doc></doc>");
print "tostring: ",$promod->toString ;
1;
------------------------------------
problem is
output ok but apache segfault
-------------------
here is a complete debug trace (this one is certified exact)
