Question

Does anyone had this problem ? When searching a partition with recursive_directory_iterator, when it reaches the end it crashes.
I get this in Visual Studio 2008 with boost 1.39 but also at home using MinGW with boost 1.46. I don’t think I am doing something wrong:

#include "stdafx.h"
#include <iostream>
#include <boost/filesystem.hpp>
using namespace std;




int _tmain(int argc, _TCHAR* argv[])
{
    boost::filesystem::path musicPaths("d:\\");
    for(boost::filesystem::recursive_directory_iterator it(musicPaths); it != boost::filesystem::recursive_directory_iterator(); ++it)
    {
        string strToFind = ".mp3";
        boost::filesystem::path dummypath = it->path().filename();
        string str = dummypath.string();
        if(str.find(strToFind) != -1)
        {
            cout << str << endl;
        }
    }
    return 0;
}

EDIT:
I see that it doesnt crash at the end but when it reaches System Volume Information

Windows does not allow you to look inside the directory “System Volume Information”.
So unleashing a recursive_directory_iterator on “System Volume Information” is a bad idea.

Edit: You may be able to solve the problem with recursive_directory_iterator::no_push(). From The Boost docs:

void no_push(bool value=true);

    Requires: *this != recursive_directory_iterator().

    Postcondition: no_push_pending() == value.

    Throws: Nothing.

    [Note: no_push() is used to prevent unwanted recursion into a directory. --end note]
