Hello.

I tried to upgrade from 10.0-RELEASE:

# freebsd-update -r 10.3-RELEASE upgrade
...
# freebsd-update install
...
# reboot
...
# freebsd-update install
Installing updates...Segmentation fault (core dumped)
Segmentation fault (core dumped)
Segmentation fault (core dumped)
Segmentation fault (core dumped)
Segmentation fault (core dumped)
Segmentation fault (core dumped)
Segmentation fault (core dumped)
Segmentation fault (core dumped)

Now I have:
# freebsd-version -ku
10.3-RELEASE-p4
10.0-RELEASE

It's not looking good. How to fix?

PS. In /var/log/messages I see "(gunzip), uid 0: exited on signal 11"
And yes:
# gunzip
