1578	bug in readdir_r_simulator() in a multi-threaded environment	raulh39@…	Beman Dawes	"g++, Boost 1.34.1, SunOs 5.7, and a multi-threaded environment.

This program never ends:
{{{
#include <boost/filesystem/fstream.hpp>
#include <boost/filesystem/operations.hpp>
#include <boost/filesystem/convenience.hpp>
#include <boost/foreach.hpp>

#include <iostream>

int main()
{
    namespace fs = boost::filesystem;

    fs::path path(""."",fs::native);
    if(fs::exists(path) && fs::is_directory(path))
    {
        fs::directory_iterator begin(path), end;
        BOOST_FOREACH(fs::path file, std::make_pair(begin,end))
            std::cout << file.leaf() << std::endl;
    }
}
}}}

The problem is that the function  readdir_r_simulator() in boost/libs/filesystem/src/operations.cpp should return != 0 to signal error, but this line:
{{{
{ return ::readdir_r( dirp, entry, result ); }
}}}
returns 0 when readdir_r() returns NULL, which means an error.

The attached patch should fix the problem.
