Mark,

I'd run into this problem a few years ago, but never had a chance
to get to the bottom of it.  From running ktrace, it looks like
this problem is related to vfork.  For me, running tcsh with the
-F flag (ie., use fork not vfork) seems to work around the problem.

I'm guessing what is happening is that something is handling the
arg too long error and clobbering the vforked stack.  I'll try to
do a bit more digging, but you might like to check if-F helps in
your case too...

	David.
