[pkg-boost-devel] Bug#448576: libboost-dev: format_date_parser::parse_date(string, string, special) doesn't compile due to wrong stringstream_type

[Max Kirillov]

Package: libboost-dev
Version: 1.34.1-2
Severity: important

consider this code:
--------------------
#include <boost/date_time/gregorian/greg_date.hpp>
#include <boost/date_time/format_date_parser.hpp>
#include <boost/date_time/special_values_parser.hpp>
#include <locale>

int
main ()
{
  boost::date_time::format_date_parser<boost::gregorian::date, char>
      parser(std::string("%Y-%m-%d"), std::locale("C"));
  boost::date_time::special_values_parser<boost::gregorian::date, char>
	  special_parser("a", "a", "a", "a", "a");
  parser.parse_date("2007-01-01", "%Y-%m-%d", special_parser);
  return 0;
}
--------------------

it failed to compile with the following message (strings wrapped):
--------------------
max at src$g++ 1.cpp
/usr/include/boost/date_time/format_date_parser.hpp: In member function
'date_type boost::date_time::format_date_parser<date_type,
charT>::parse_date(const std::basic_string<charT, std::char_traits<_CharT>,
std::allocator<_T2> >&, const std::basic_string<charT,
std::char_traits<_CharT>, std::allocator<_T2> >&, const
boost::date_time::special_values_parser<date_type, charT>&) const [with
date_type = boost::gregorian::date, charT = char]':

argument 1 of 'std::istreambuf_iterator<_CharT,
_Traits>::istreambuf_iterator(std::basic_streambuf<_CharT, _Traits>*) [with
_CharT = char, _Traits = std::char_traits<char>]'
--------------------

the code in the header is:
--------------------
  typedef std::basic_ostringstream<charT>  stringstream_type;
  typedef std::istreambuf_iterator<charT> stream_itr_type;

   ....

  date_type
  parse_date(const string_type& value, 
             const string_type& format_str,
             const special_values_parser<date_type,charT>& sv_parser) const
  {
    stringstream_type ss;
    ss << value; 
    stream_itr_type sitr(ss);
    stream_itr_type stream_end;
    return parse_date(sitr, stream_end, format_str, sv_parser);
  }
--------------------

I think, istream_iterator should not be constructed from ostream.

PS: I should report it to the upstream but have problems
with their trac form, please somebody tell them.
