I can make calls to m_nodeList.size() and empty() without a problem, it's just the begin one. The error I get is "The application has requested the runtime to terminate in an unusual way..."

You do it wrong. get_children return a list container that should 
contain all children elements. However if there is no children of that 
node get_children returns empty list. You must check if list contains 
something. You can do it like this:

    xmlpp::Node::NodeList nl = node->get_children();
    if ( !nl.empty() ) {
      xmlpp::Node::NodeList::iterator it = nl.begin();
      //other code here
    }
