Please see https://launchpad.net/~hartmans/+archive/ubuntu/krb5  for
trusty packages that should fix the problem.

Can I get confirmation from Tom or someone else that without these
packages trusty fails the reproduce test in comment #1 and with them, it
succeeds the test proposed in comment #1?

I'm updating a branch I have for proposed trustry krb5 updates
(lp:~hartmans/ubuntu/trusty/krb5/gss-infinite-loop) to include this
patch.

  krb5 database propagation enters infinite loop

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.
