istream_iterator in spirit might have defect

[Li He <I.demonstrate@…>]

The following program yields a wrong parsing result:

#include <iostream>
#include <vector>
#include <algorithm>
#include <iterator>

#include <boost/spirit/include/qi.hpp>
#include <boost/spirit/include/phoenix_core.hpp>
#include <boost/spirit/include/phoenix_operator.hpp>
#include <boost/spirit/include/phoenix_stl.hpp>

namespace spirit = boost::spirit ;
namespace qi = boost::spirit::qi ;
namespace ascii = boost::spirit::ascii ;
namespace phoenix = boost::phoenix ;

using qi::double_ ;
using qi::_1 ;
using phoenix::push_back ;
using phoenix::ref ;

int
main (int argc, char* argv[]) {
  spirit::istream_iterator iter (std::cin), end ;
  std::vector<double> v ;
  bool r = spirit::qi::phrase_parse
    (iter, end,
     double_ [push_back (ref(v), _1)] % ',',
     ascii::space) ;

  if (r) {
    std::cout << "vector: " ;
    std::copy (v.begin(), v.end(),
               std::ostream_iterator<double> (std::cout, ", ")) ;
    std::cout << std::endl ;
  }
  return 0 ;
}

You may test it with input like "1,2,3,4" and the output is "vector: 1,2,3,44,". When we switch to std::getline and use the std::string::const_iterator, the result turns out fine.

Cannot reproduce, it prints vector: 1, 2, 3, 4, for me.
