[systemd-devel] Possible systemd segfault switching from 216 to 219 in fedora upgrade

I spent some time last night trying to track down the issue preventing
fedup from fedora 21 to 22:
I'm pretty sure I've tracked it down to when switch-root is called and
systemd-219 gets executed being passed the serialised state of systemd-216
in the process.
Unfortunately when this occurs the whole system is brought to a halt making
further debugging tricky.
Any ideas on how I might reproduce on a reduced an BBS simplified testcase
for the behaviour involved?
There is strace of pid1 from just before the switch-root to the crash along
with coredumps that have been generated on the bug.
These tests were carried out with enforcing=0 at the kernel command line so
I'm reasonably confident the bug is not SELinux related.
