9483	Can't get (translate) literal values with suffixes out of ptree	Ricardo Abreu <ricardolafabreu@…>	Sebastian Redl	"Hello,

I just figured that the property_tree lib cannot translate some acceptable literals. Here is an example to show this:

{{{
#include <boost/property_tree/ptree.hpp>
#include <boost/optional.hpp>
#include <iostream>

using namespace boost::property_tree;
using namespace std;

void printo(boost::optional<long long> o, const std::string & name)
{
    if(o)
      cout << name << "" is: "" << *o << endl;
    else 
      cerr << ""couldn't get "" << name << endl;
}

int main()
{
  ptree p;
  p.put(""good_long_long"", ""0"");
  long long test1 = 0; // show that 0 is an acceptable long long literal
  p.put(""bad_long_long"", ""0LL"");
  long long test2 = 0LL; // show that 0LL is an acceptable long long literal
  auto good = p.get_optional<long long>(""good_long_long"");
  auto bad = p.get_optional<long long>(""bad_long_long"");
  printo(good, ""good"");
  printo(bad, ""bad"");

  return 0;
}
}}}

Apparently the stream_translator doesn't consume the 'L's and then the test {{{iss.get() != Traits::eof()}}}, in stream_translator.hpp, is true, resulting in an empty optional.

Please feel free to contact me. I hope not, but I'm sorry if there is something stupid I am missing.

Cheers,
