[Bug 1592841] Re: FTBFS on ppc64el, blocks updates of all packages depending on krb5, for example CUPS

[Till Kamppeter]

With your last debdiff I was able to generate a source package which I
have uploaded to my PPA (ppc64el activated before) but it still does not
build on ppc64el. Here is the build log:

yakkety-ppc64el.krb5_1.14.2+dfsg-1ubuntu1+ppa2_BUILDING.txt.gz

Title:
  FTBFS on ppc64el, blocks updates of all packages depending on krb5,
  for example CUPS

Status in krb5 package in Ubuntu:
  New

Bug description:
  krb5 in Yakkety, version 1.14.2+dfsg-1 does not build on ppc64el and
  so it does not make it from -proposed into release. This blocks
  packages which depend on krb5, like CUPS, from getting from -proposed
  to release, preventing further development on the main platforms
  (amd64, i386, ...) due to the failure on this more exotic platform.

  Other packages depending on krb5 and so suffering the same problem as
  CUPS are: libkdb5, openssh-server, dnsutils, cvs, libkadm5clnt-mit9,
  libkadm5srv-mit9, libdns162, unity-control-center, libdns100.

  cjwatson on IRC, channel #ubuntu-release about this FTBFS and a
  possible fix:

  I suspect it's due to -O3
   Looks like the sort of thing where the compiler does a bit more uninitialised-variable tracking at higher optimisation levels
   Would probably go away at -O2, or somebody could adjust the offending function to pacify the compiler; either way
