Thanks for your reply. So you're saying that the behavior of shared_ptr is
correct (perfectly fine with me). But then I have to say, that the
documentation of shared_ptr located under
http://www.boost.org/doc/libs/1_39_0/libs/smart_ptr/shared_ptr.htm#constructors
is wrong, because it says that if you construct a shared_ptr from a weak_ptr
(!) the use_count will *not* change.
