            Bug ID: 213506
           Summary: YP/NIS: yppush, ypxfr dump core
           Product: Base System
           Version: 11.0-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: bin
          Assignee: freebsd-bugs at FreeBSD.org

I have a YP (NIS) setup with one master server and several slave servers. One
of the latter is in ypservers (together with the master server, as setup by
ypinit -m).

If I modify a YP-relevant file on the master server and do a 'make' in /var/yp,
yppush fails with a segmentation violation (signal 11) and dumps core. This
aborts 'make', thereby not processing the remaining maps.

If I manually ypxfr a map from the master to any of the slave servers (invoked
at the respective slave server as "ypxfr -h <master server> <map name>"), ypxfr
fails with a segmentation violation (signal 11) and dumps core. It leaves a
zero-sized file in /var/yp/<domainname> with a .nnnn suffix, e.g.,

None of this happened with 10.3.

Btw, the only maps which can be successfully transferred are empty ones, i.e.,
containing no entries. The associated file in /var/yp/<domainname> has a size
of 40960 bytes.

One more note: this started to happen several months ago on 11-current compiled
for armv6. At that time I thought it was just a problem on that architecture.
But now, after installing 11.0 on all my machines, it happens on all of them
(amd64 and i386).
