The following script gives an error on the SELECT statement:

<blockquote><verbatim>
CREATE TABLE t1 (a INTEGER PRIMARY KEY);
CREATE TABLE t2 (a INTEGER PRIMARY KEY, b INTEGER);
CREATE TABLE t2x (b INTEGER PRIMARY KEY);
SELECT t1.a FROM ((t1 JOIN t2 ON t1.a=t2.a) AS x JOIN t2x ON x.b=t2x.b) as y;


The error only occurs if the name of the third table includes the name
of the second table as a prefix.  This problem was introduced by
check-in [99127a669c] on 2013-01-03 and has never appeared in an official
release.
