SQLite

Henry Liu of Shenzhen Ankki Technologies Co.Ltd. sent in the following script which causes a fault in the renameTokenCheckAll() routine:

CREATE TABLE a(a);
CREATE VIEW b AS SELECT(SELECT *FROM c JOIN a USING(d, a, a, a) JOIN a) IN();
ALTER TABLE a RENAME a TO e;

Henry reports that this asserts, but I only see failures if I run under valgrind. Note that fault is in the error-checking routine renameTokenCheckAll(). That routine only runs in debugging mode. For release builds, this routine is a no-op and so the fault never occurs.
