At the time, I hadn't.

I now have.  And I find that the problem is there (still or again,
whichever, though I suspect it's "still") in an ftp binary built from
the sup of Dec 31.  (And in passing, I'll note I'm somewhat ticked to
have sent-pr a problem, had the pr closed with "fixed in current", and
then find it's still there months later, in a release.  Perry, if you
still can't reproduce this, I can give you a login on an affected
machine so you can try it for yourself; contact me privately if you
want to take me up on that.)  I do have my patches applied to this
source tree, but no patches at all to usr.bin/ftp or lib/libedit.

This is on the serial console of a SS1+, though past experience
indicates it happens on ptys too.  "stty everything" reports

speed 9600 baud; 0 rows; 0 columns;

When I run ftp, I see the following.  (I typed ^Z at each of the first
two "ftp> " prompts, then RETURN when nothing happened.)

kdump output is rather large; I can supply it in full if desired.  Here
are what I think are relevant excerpts:
