backend crash with certain statements/tables

Reproduced in PG 7.4.1 on ...

OS X Server 10.2.8
OS X 10.2.8
RHL 9 (2.4.20-30.9)

Running any of these statements on my database causes the backend to
crash (example from PG log below):

create temp table foo as select * from server_prefs limit 1;
create table foo as select * from server_prefs limit 1;
create temp table foo as select * from agency_dbs limit 1;
create table foo as select * from agency_dbs limit 1;


All of these statements produce expected results (no crash):

create temp table foo as select * from c_group limit 1;
create table foo as select * from c_group limit 1;
create table foo as select * from server_prefs;
create table foo as select * from agency_dbs;
select * from server_prefs limit 1;
select * from agency_dbs limit 1;


Attached is a file that creates a database and only the server_prefs
table and then reproduces the crash for me on both OS X and Linux
when I run it like:

    psql -d template1 -U postgres -f pg_crash

Thanks,
- Jeff
