[libxml++] different behavior on solaris/x86 and linux/x86 of Document::create_root_node?

[Tim Flechtner <timf trdlnk com>]

i wrote a short program:
#include <iostream>

#include <libxml++/libxml++.h>

using namespace std;
using namespace xmlpp;

main()
{
try {
    xmlpp::Document document;
    xmlpp::Node* nodeRoot = document.create_root_node("exampleroot");
    cout << nodeRoot << endl;
} catch(const std::exception& ex) {
  cout << "Exception \"" << ex.what() << "\"" << endl;
}


which on my solaris x86 box cout's 0, and on linux cout's a valid 
address.  both platforms are using gcc-3.2.3.  has anyone else run into 
this?

here is the solaris/x86 ldd:
	libxml++-0.1.so.10 =>	 /opt/Gcc3/gnome/2.2/lib/libxml++-0.1.so.10
	libxml2.so.2 =>	 /opt/Gcc3/lib/libxml2.so.2

and the linux/x86 ldd:
