I feel a little bit sheepish about my lack of knowledge about Solaris and SysV kernels in general, but what a place to learn. :-) Many thanks to those who have replied to me directly or to the list.

Another correspondant mentioned that clobbering an additional two structure members, the "saved" uid & gid, might be useful, too. From <sys/cred.h>: typedef struct cred { ulong_t cr_ref; /* reference count */ uid_t cr_uid; /* effective user id */ gid_t cr_gid; /* effective group id */ uid_t cr_ruid; /* real user id */ gid_t cr_rgid; /* real group id */ uid_t cr_suid; /* "saved" user id (from exec) */ gid_t cr_sgid; /* "saved" group id (from exec) */ ulong_t cr_ngroups; /* number of groups in cr_groups */ gid_t cr_groups[1]; /* supplementary group list */ } cred_t; That brings the magic Forth to: 19 4 do {uid} {addr} 24 + l@ i + l! 4 +loop -Scott --- Scott E.
