Avoid leaking Index.aiRowEst memory if an OOM causes a rollback which deletes the index before the aiRowEst deletion code in sqlite3AnalysisLoad() routine has a chance to run. Since the aiRowEst now might be deleted from freeIndex() which does not always have a db pointer, make sure the aiRowEst memory is not held in lookaside. check-in: efd87ba1 user: drh tags: stat4-avgeq
