| 21:36 | Ensure that the KeyInfo.nXField value for ephemeral tables used to implement ORDER BY or GROUP BY clauses is set correctly, so that the sqlite3VdbeFindCompare() routine can choose the correct comparison function. Add assert() statements to the high-speed comparison functions to detect cases where they are inappropriately chosen. Fix for ticket [f97c4637102a3ae72b7911].
