I see this problem on NetBSD-2.0_BETA as well.  The symptom is
that if I run this interactively, it will process the command,
spit out all the prefixes, return with a prompt, and when that
prompt is given EOF, it crashes.

I tried running ut under gdb, and have a stack trace, but I
suspect that the debugging info is somehow faulty (I don't
understand why the code points to the line it does).  For what
it's worth, here it is:
