[boost] shifted_ptr crash quest & intrusive_list revival

Greetings:

I have uploaded a cleaner version of shifted_ptr including better intrusive 
containers (intrusive_list & intrusive_stack) stripped from redundant 
information.  The containers were initialy designed for shifted_ptr but 
proposes an interface that could be extended from ground up.  Indeed, in 
this concept containers have no idea what the element_type is; it only knows 
about pointers to nodes.  The responsability of knowing about the 
element_type is forwarded to the iterator, usualy using within a loop, which 
is eventually dereferenced appropriately.  Having stricter containers could 
have been there but this is primaly a tool that is adapted to shifted_ptr 
and removes a lot of forward declarations because the type needs not be 
known.

Secondly right now I would be happy to learn segfault are detected using 
shifted_ptr.  Please provide simple case scenarios and I will trace the 
problem.  This is not yet multithreaded and compiles fine only on x86:
