The workaround suggested (https://github.com/krb5/krb5/commit/26d8744129) is still valid, and appears on upstream's 1.12 release branch already (as https://github.com/krb5/krb5/commit/c7bb9278ad12c9). It will appear in the 1.12.2 release. Furthermore, I have applied it to the Debian packaging as http://anonscm.debian.org/cgit/pkg-k5-afs/debian- krb5-2013.git/commit/?id=3d3bf0c075af62f278b6 (though it has not yet been uploaded to Debian proper). This workaround should not introduce any regressions.
I should also note that, if I understand correctly, we expect a no- change rebuild of krb5 using the gcc currently in utopic to also be a valid workaround. However, the gcc in trusty is still expected to produce krb5 packages which exhibit this bug. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to gcc-4.8 in Ubuntu. https://bugs.launchpad.net/bugs/1347147 Title: krb5 database propagation enters infinite loop Status in The GNU Compiler Collection: Unknown Status in Network Authentication System: Unknown Status in “gcc-4.8” package in Ubuntu: New Status in “krb5” package in Ubuntu: Triaged Bug description: 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.
