libxml++ is a wrapper around libxml2. The latter provides a callback
mechanism to notify the wrapper whenever a xmlNode is created/destroyed.
In document.cc a function 'construct' is registered with libxml2 that is
responsible to allocate wrapper objects, pointed to by the various _private
members.

Please test whether the Document::Init constructor is actually called, as
this is the place where the callbacks are initialized. It seems that isn't
working right for you. May be this is a bug in msvc 6 not initializing the
Document::_init object...
