The first argument to qi::parse is a non-const reference (which fails on the
temporary you're passing in).
Try:

  std::string::iterator ii = str.begin();
  boost::spirit::qi::parse(ii, str.end(),
           raw[+~string(delim)] % lit(delim), result);

Spirit uses the first parameter to return how far it got in the parsing of
your string.
