regression in CVS HEAD

Running CVS HEAD from this morning, 'make check' fails due to an
initdb failure when initializing pg_depend:

initializing pg_depend...
/home/nconway/pgsql/src/test/regress/./tmp_check/install//data/pgsql/bin/initdb:
line 718: 31128 Segmentation fault      (core dumped) "$PGPATH"/postgres
$PGSQL_OPT template1 >/dev/null  <<EOF

That corresponds to the following lines in initdb, which lead to the
core dump:

DELETE FROM pg_depend;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_class;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_proc;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_type;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_constraint;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_attrdef;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_language;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_operator;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_rewrite;
INSERT INTO pg_depend SELECT 0,0,0, tableoid,oid,0, 'p' FROM pg_trigger;

Here's the backtrace from the core dump:

Can someone fix this please?
