CREATE TABLE ... PRIMARY KEY kills backend

Using the cvs version updated this morning, this query kills the backend,
with no explanation in the log (-d 3):

  create table junk (id char(4) primary key, name text not null)

If the primary key constraint is omitted, it is OK.

This worked yesterday.  Is this a solved problem, or do I need to trace it?
