8946	filesystem::directory_iterator returns incorrect listing	l.alebarde@…	Beman Dawes	"Both '''directory_iterator''' and '''recursive_directory_iterator''' do not work correctly under linux with g++-4.7.3 : one item, assumed to be the last one, is not listed.

Simple code to reproduce the problem :
{{{
#include <iostream>
#include <stdio.h>
#include <boost/filesystem.hpp>

using namespace std;
namespace bfs = boost::filesystem;

int main () {
	system(""mkdir mydir"");
	system(""touch mydir/file1"");
	system(""touch mydir/file2"");
	bfs::directory_iterator bfs_dir_i_end;
	bfs::directory_iterator bfs_dir_i(""mydir/."");
	while (++bfs_dir_i != bfs_dir_i_end) {
		bfs::file_type type = (*bfs_dir_i).status().type();
		bfs::path source = (*bfs_dir_i).path();
		cout << source << ""  "" << type << endl;
	}
}
}}}

Build with :
{{{
g++-4.7.3 -I/usr/include/crypto++ -O0 -g3 -Wall -c -fmessage-length=0  -std=c++11 show_bug_directory_iterator.cpp
g++-4.7.3 -lboost_filesystem -o show_bug_directory_iterator show_bug_directory_iterator.o
}}}

Code result :
{{{
$ ./show_bug_directory_iterator
""mydir/./file1""  2
}}}

Should be :
{{{
$ ./show_bug_directory_iterator
""mydir/./file1""  2
""mydir/./file2""  2
}}}

Shell result :
{{{
$ ls -lR .
.:

drwxr-xr-x 2 alain alain    4096 31 juil. 10:48 mydir

Notes :
  1) Not tested under other gcc versions.

  2) Tested with same results on Boost 1.52.0 and 1.53.0

  3) suspected regression, cf [https://svn.boost.org/trac/boost/ticket/257]"	Bugs	new	To Be Determined	filesystem	Boost 1.54.0	Problem		directory_iterator
