Comment (by gast128@…):

 This is breaking for us and still present in 1.66. We look at the Visual
 Studio output and it should be clean. Once memory leak reports appear
 there one won't be able to distinguish a benign one from a serious one.

 The destructor of the singleton (which would free the memory) is never
 called. Trying to work around and making a singleton by hand leads to a
 stack overflow (0xC00000FD):

 {{{#!cpp
 struct Bla
 {
     template <class Archive>
     void serialize(Archive& ar, const unsigned int version)
     {
         ar & boost::serialization::make_nvp("m_n", m_n);
     }

     int m_n;
 };

 const
 boost::serialization::singleton<boost::serialization::extended_type_info_typeid<Bla>>
 g_singleton;
 }}}
