Under FreeBSD-2.2-SNAP with the same version of pdksh, I used to use a
.kshrc like the following, and never encountered any problems. Under
FreeBSD-3.0-SNAP, this same script does something that causes future
invocations of /bin/sh to core dump?  Using pdksh withOUT this rc script
does NOT cause /bin/sh to dump, so it is specific to this script, which
as I mentioned earlier, worked just fine under FreeBSD-2.2.
