      Joe,

   On a Gould 6080 running UTX2.0u06 (mostly 4.3ish) with a number of
local hacks, the csh did not dump, but the tcsh did.  A quick look with
adb showed that tcsh was calling strcmp with a NULL pointer.  On a Gould
with "protection hardware" de-referencing a NULL pointer results in a
protection violation and a core dump.  It looks like the builtin echo in
the tcsh does not check it's arguments.

   Given that tcsh is derived from csh, I suspect that you are
experiencing similar troubles.  The csh we are running here is newer
than the csh that our installed tcsh is based on.  A new, as yet
uninstalled, version of tcsh based on the newer csh also passes your
test.
				Later,
				    Bob
