| 19:23 | Add tail recursion to the sqlite3ExprDelete() routine in order to keep down stack space usage for really, really large expressions. Later: The tail recursion is dangerous since the recursion might happen after the expression has been freed. (check-in: 7324c7f2f8 user: drh tags: mistake) | |
