Segfault

Another test configuration, another segfault. ;) Admittedly, I'd doing some odd stuff, like dual afr membership like so on the client:
afr-ns = a-ns, b-ns
afr1 = a-ds, b-ds
afr1 = b-ds, a-ds
unify = afr1, afr2 / ns = afr-ns

Servers simply export a namespace (ns) and a posix-locked share (ds).

Clients and servers start fine, any access from the client causes both servers to segfault as below.

Yes, I'm aware this may not be a supported configuration, I just figured I'd try, and then see how locking worked (as I can see there might be a posix locking problem with this if it doesn't segfault).
