Comment:

 This is a very old bug, sorry for missing it. Boost.Move has its
 limitations, and Boost.Container can't do anything with this. But at least
 in old compilers like MSVC-7.1 recent BOOST_MOVE_RET makes this example
 work:

 {{{

 #include <boost/container/vector.hpp>

 //A non-copyable type
 #include "movable_int.hpp"

 typedef boost::container::vector<boost::container::test::movable_int>
 VecType;

 VecType some_other_vec;

 VecType foo()
 {
    return BOOST_MOVE_RET(VecType, some_other_vec);
 }

 int main()
 {
    VecType x= foo();
    return 0;
 }

 }}}

 Sadly there is little Boost.Container can do if this Boost.Move workaround
 does not work in your compiler. I hope this helps.
