Build conflict with Eigen

>prettyprint.hpp(117): error C3313: 'it': variable cannot have the type 'void'

        template <typename U>
        struct printer
        {
            static void print_body(const U & c, ostream_type & stream)
            {
                using std::begin;
                using std::end;

                auto it = begin(c); //<<< The error is here
                const auto the_end = end(c);

                if (it != the_end)
                {
                    for ( ; ; )
                    {
                        stream << *it;

                    if (++it == the_end) break;

                    if (delimiters_type::values.delimiter != NULL)
                        stream << delimiters_type::values.delimiter;
                    }
                }
            }
        };

It seems that some Eigen containers are detected as iterable: has_begin_end && has_const_iterator are true, but when using it begin and end function returns a void iterator.

As someone faced the same issue?
Is there a way to check that begin/end should not be void?
