Public bug reported: In some conditions, propagating a kerberos database to a slave KDC server can stall. This is due to a misoptimization by gcc 4.8 of the CIRCLEQ famliy of macros, apparently due to overzealous strict aliasing deductions.
One case of this stall is reported at http://mailman.mit.edu/pipermail/kerberos/2014-July/020007.html (and the rest of the thread), and there is an entry in the upstream bugtracker at http://krbdev.mit.edu/rt/Ticket/Display.html?id=7860 . gcc 4.9 (as used in Debian unstable at present) is not believed to induce this problem. Upstream has patched their code to use the TAILQ family of macros instead, as a workaround, but that workaround has not yet appeared in an upstream release: https://github.com/krb5/krb5/commit/26d8744129 Because of the different compiler versions used on Debian and Ubuntu, I am filing this as an Ubuntu-specific bug. ** Affects: krb5 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1347147 Title: krb5 database propagation enters infinite loop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/krb5/+bug/1347147/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
