Hello, Using boost version 1.34.1 I get an assertion failure when comparing recursive_directory_iterator to the end iterator if the corresponding path comprises an empty directory. // a directory that is not empty - runs OK //boost::filesystem::path boostPath("C:\\test_notempty"); // a directory that is empty - crashes boost::filesystem::path boostPath("C:\\test_empty"); if (boost::filesystem::is_directory(boostPath)) { boost::filesystem::recursive_directory_iterator end_itr; for (boost::filesystem::recursive_directory_iterator itr(boostPath); itr != end_itr; ++itr) { std::cout << itr->path().string() << std::endl; } } Assertion failed: m_imp.get() && "attempt to dereference end iterator", file c:\ program files\boost\boost_1_34_1\boost\filesystem\operations.hpp, line 849 This issue has been reported before: http://lists.boost.org/Archives/boost/2006/10/111230.php What's the workaround? I can't seem to find any way to inspect the path or its iterator to distinguish an empty directory from a nonempty one without crashing the program. Thanks, Eric
