Prevent the printf formatter from doing large memory allocations - larger than either the size of the static buffer for interfaces like sqlite3_snprintf(), or larger than SQLITE_LIMIT_LENGTH for interfaces that are associated with a database connection. This helps to prevent DOS attacks on products that let hostile sources inject arbitrary SQL. It also helps fuzzers run faster and more effectively. (check-in: 179e5d4605 user: drh tags: trunk)

Ensure that the Walker.pParse structure is initialized when walking the source tree to gather the WINDOW clauses on a query with window functions. (check-in: 4ca9d5d53d user: drh tags: trunk)
