 Tested with gcc 4.6 on MacOSX, this simple piece of code throws a
 std::bad_cast exception with Boost 1.45.0

 I found a quick fix.

 Replace this :

 {{{
 #!div style="font-size: 80%"
 include/boost/archive/basic_binary_oprimitive.hpp
   {{{#!cpp
 108     BOOST_ARCHIVE_OR_WARCHIVE_DECL(BOOST_PP_EMPTY())
 109     basic_binary_oprimitive(
 110         std::basic_streambuf<Elem, Tr> & sb,
 111         bool no_codecvt
 112     );
   }}}
 }}}

 By this :

 {{{
 #!div style="font-size: 80%"
 include/boost/archive/basic_binary_oprimitive.hpp
   {{{#!cpp
 108     BOOST_ARCHIVE_OR_WARCHIVE_DECL(BOOST_PP_EMPTY())
 109     basic_binary_oprimitive(
 110         std::basic_streambuf<Elem, Tr> & sb,
 111         bool no_codecvt
 112     ) : m_sb( sb )
 113     #ifndef BOOST_NO_STD_LOCALE
 114       , locale_saver( sb )
 115     #endif
 116     {};

   }}}
 }}}

 Same modifications for the file basic_binary_'''i'''primitive.hpp.

 I'm not sure this is the right thing to do, and I don't understand why the
 constructor didn't have any body.
 Is there a default behavior for that kind of constructor ?
