You're receiving this bug because the package in Summary has produced _FORTIFY_SOURCE related warnings indicating the presence of a sure overflow in a static buffer. Even though this is not always an indication of a security problem it might even be. So please check this out ASAP. By the way, _FORTIFY_SOURCE is disabled when you disable optimisation, so don't try finding out the cause using -O0. Thanks, Your friendly neighborhood tinderboxer
