 bug (backtrace, line number that triggers this error)

 try it on MSVC2008. If you have this one.

 compiler didn't find specialization for detail::lcast_src_length so
 sizeof(buf) is 2 bytes:
 {{{
 std::size_t const src_len = lcast_src_length::value;
 char_type buf[src_len + 1]; // src_len equal 1 here
 }}}

 fix:
 {{{
 < typedef BOOST_DEDUCED_TYPENAME
 detail::array_to_pointer_decay<Source>::type src;
 ---
 > typedef BOOST_DEDUCED_TYPENAME
 detail::array_to_pointer_decay<boost::remove_cv<Source>::type>::type src;
 }}}
