[pkg-apparmor] Bug#768980: apparmor_parser sometimes crashes with "free(): invalid next size (normal): 0x00000000009915a0"

[intrigeri at debian.org]

Package: apparmor
Version: 2.9.0-2
Severity: important

As reported on https://bugs.debian.org/768699, sometimes
apparmor_parser crashes with this message:

  free(): invalid next size (normal): 0x00000000009915a0

The full log that exposes it can be found there:

  http://aws-logs.debian.net/ftbfs-logs/2014/11/08/apparmor-profiles-extra_1.4_jessie.log

I could reproduce it neither in a Jessie/amd64 chroot, nor in
a sid/amd64 one.
