Hello,
Does boost got something to do this
  struct node {
    std::vector<node> children; // node is incomplete
  };
in a way which conform with the standard which disallows STL containers of
incomplete types?
thx,

This issue strikes boost.property_tree
<boost/ptree.hpp>
    ...
    template<class C, class K, class P, class D, class X>
    class basic_ptree
    {
    ...
        typedef basic_ptree<C, K, P, D, X> self_type;
    ...
        typedef std::pair<key_type, self_type> value_type; 
        // ..self_type is incomplete!
    ...
        typedef std::list<value_type> container_type;
    ...
        container_type m_container;
<boost/ptree.hpp>

PS: I had to apply this 
  <link>
http://article.gmane.org/gmane.comp.lib.boost.devel/164866/match=property%5f...
  </link>
to get 
  libs/property_tree/test/sandbox.cpp
compiled.
