------------------------------+---------------------------------------------
 When trying to construct a directory_iterator from a location that doesn't
 exist anymore, no exception is thrown.

 This code in directory_iterator_increment fails:

 if (temp_ec)
       {
         it.m_imp.reset();
         if (ec == 0)
           BOOST_FILESYSTEM_THROW(
 filesystem_error("boost::filesystem::directory_iterator::operator++",
               it.m_imp->dir_entry.path().parent_path(),
               error_code(BOOST_ERRNO, system_category())));
         ec->assign(BOOST_ERRNO, system_category());
         return;
       }

 it.m_imp is first reset and then used while trying to throw an exception.
