1299	change in typedef stringstream_type in format_date_parser.hpp causing compilation error	anonymous	az_sw_dude	"In format_date_parser.hpp, the typedef '''stringstream_type''' (in class format_date_parser) was defined as

'''std::basic_stringstream<charT>'''

in boost-1.33.0 but now has changed to 

'''std::basic_ostringstream<charT>'''

in boost-1.34.1. This change now causes compilation error to any call to the function  ->

  date_type[[BR]]
  parse_date(const string_type& value,[[BR]]
             const string_type& format_str,[[BR]]
             const special_values_parser<date_type,charT>& sv_parser) const[[BR]]
  {
    stringstream_type ss;[[BR]]
    ss << value;[[BR]]
    stream_itr_type sitr(ss); // THIS ERROR IS IN THIS LINE !!

    stream_itr_type stream_end;[[BR]]
    return parse_date(sitr, stream_end, format_str, sv_parser);[[BR]]
  }

The compiler error (for boost-1.34.1) is ->

'''format_date_parser.hpp:221: error: invalid conversion from `void*' to
`std::basic_streambuf<char, std::char_traits<char> >*''''

and is observed with multiple versions of gcc (3.4.x and 4.x).


Here's a simple example ->

{{{
#include <sstream>
int main()
{
  typedef std::basic_ostringstream<char>  stringstream_type;
  typedef std::istreambuf_iterator<char> stream_itr_type;

stringstream_type ss;
stream_itr_type itr(ss);
return 0;
}
}}}

The above program does not compile unless stringstream_type is changed to std::basic_stringstream<char>."	Bugs	closed	To Be Determined	date_time	Boost 1.38.0	Showstopper	fixed
