| Comment: | New test case that still hits an assertion fault, just to prove that the previous checkin merely made the problem more obscure and did not completely fix it. |

| 22:04 | Fix the sqlite3ExprDup() routine so that it makes complete duplications of subqueries containing window functions. (check-in: 94017454 user: drh tags: ticket-f09fcd17810f) | |

| 19:15 | Simplify the query flattener so that it does not duplicate the WHERE clause of subquery that is being incorporated into the outer query - copies it directly. This is more efficient. And it also fixes the specific test case show for ticket [f09fcd17810f65f71789525] but it does not resolve the more general problem that sqlite3ExprDup() does not correctly duplicate expressions that contain subqueries with window functions.
