I tried your code (modifying argv[1]) and it did not work on 10.6.3 either. Do you mean modifying memset() can change output of ps for built-in processes (xterm, expect, ssh, bash...) in my first post?
Thanks,
D.
I meant that the following works on 10.4.11, for clearing out all argument strings pointed to from argv (which usually show up in ps output):
You cannot do this from a shell script, though. Also, even if you could, there is a race condition present. The args could be visible from ps if ps is run at just the right time and the kernel's process scheduler conspires against you.
As Corona has made clear, there is no secure way to accomplish what you're trying to do. The best you can manage is a few obstacles to keep the undetermined at bay.

ssh-argv0
SSH-ARGV0(1) BSD General Commands Manual SSH-ARGV0(1)NAME
ssh-argv0 -- replaces the old ssh command-name as hostname handling
SYNOPSIS
hostname | user@hostname [-l login_name] [command]
hostname | user@hostname [-afgknqstvxACNTX1246] [-b bind_address] [-c cipher_spec] [-e escape_char] [-i identity_file] [-l login_name]
[-m mac_spec] [-o option] [-p port] [-F configfile] [-L port:host:hostport] [-R port:host:hostport] [-D port] [command]
DESCRIPTION
ssh-argv0 replaces the old ssh command-name as hostname handling. If you link to this script with a hostname then executing the link is
equivalent to having executed ssh with that hostname as an argument. All other arguments are passed to ssh and will be processed normally.

See ssh(1).
FILES
