It is not something that Boost.Range should support explicitly imho as
there is no
problem with exact same code with std::vector instead of
boost::container::vector.

This is what copy_range does:

        template< typename SeqT, typename Range >
        inline SeqT copy_range( const Range& r )
        {
            return SeqT( boost::begin( r ), boost::end( r ) );
        }

Code I attached just tries to initialize boost::container::vector from
2 iterators. (Same
error when using explicit assign() method). Also copying transformed_range to a
container::vector is OK, only (re) initialization fails.

Regards,
Simon
