#6515: Serilaization of std::vector<bool> is broken for optimizing archives

     Type:  Bugs              |      Status:  new          
Milestone:  To Be Determined  |   Component:  serialization
  Version:  Boost 1.48.0      |    Severity:  Problem      
 Keywords:                    |  
------------------------------+---------------------------------------------
 Serializing a vector<bool> causes corruptions in the created archive. The
 reason is this function (in boost/serialization/vector.hpp):

 {{{
 template<class Archive, class U, class Allocator>
 inline void save(
     Archive & ar,
     const std::vector<U, Allocator> &t,
     const unsigned int /* file_version */,
     mpl::true_
 ){
     const collection_size_type count(t.size());
     ar << BOOST_SERIALIZATION_NVP(count);
     if (!t.empty())
         ar << make_array(detail::get_data(t),t.size());
 }
 }}}

 While detail::get_data(t) is not specialized for std::vector<bool> (but it
 should be), and t.size() returns the number of bits stored in the vector,
 which is probably not what's expected either.

 I'm encountering this problem with MSVC10, 64bit, Windows7.
