Ned Deily added the comment: The crash occurs in OS X's libsystem_info on 10.8.
Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libsystem_info.dylib 0x00007fff86bacd9e mdns_addrinfo + 299 1 libsystem_info.dylib 0x00007fff86badae2 search_addrinfo + 152 2 libsystem_info.dylib 0x00007fff86b97f6d si_addrinfo + 1641 3 libsystem_info.dylib 0x00007fff86b9785c getaddrinfo + 171 4 _socket.so 0x0000000100516524 socket_getaddrinfo + 500 It's also reproducible back on OS X 10.6 crashing there in libSystem. (It looks like earlier versions of OS X don't support the AI_NUMERICSERV flag.) So it would appear to be a long-standing OS X bug. Possible actions: open an Apple incident and patch socket.getaddrinfo to catch this case. ---------- nosy: +ned.deily _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue17269> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
