Comment (by stl):

 Some simplified code to reproduce the crash. As concurrency bugs are
 timing dependent, this will crash most of the time, but not always.

 {{{
 #include <boost/filesystem.hpp>
 #include <boost/thread.hpp>

 void thr()
         {
         boost::filesystem::path file(L"C:\\test");
         boost::this_thread::sleep(boost::posix_time::milliseconds(10));
         std::cout << file.string() << std::endl;
         }


 int main()
         {
         boost::thread_group tg;
         for (size_t n = 0; n < 5; ++n)
                 {
                 tg.create_thread(thr);
                 }
         tg.join_all();
         return 0;
         }

 }}}
