cd /usr/include/boost
sudo gedit /date_time/time_parsing.hpp

Remove following from libboost1.71:

    typedef special_values_parser<date_type, std::string::value_type> svp_type;

    // given to_iso_string can produce a special value string
    // then from_iso_string should be able to read a special value string
    // the special_values_parser is expensive to set up and not thread-safe
    // so it cannot be static, so we need to be careful about when we use it
    if (svp_type::likely(s)) {
        typedef typename svp_type::stringstream_type ss_type;
        typedef typename svp_type::stream_itr_type itr_type;
        typedef typename svp_type::match_results mr_type;
        svp_type p; // expensive
        mr_type mr;
        ss_type ss(s);
        itr_type itr(ss);
        itr_type end;
        if (p.match(itr, end, mr)) {
            return time_type(static_cast<special_values>(mr.current_match));
        }
    }

Which is new compared to libboost1.65.1
