| 00:29 | • Fixed ticket [3a88d85f]: Segfault when a DEFAULT value contains an aggregate function plus 5 other changes (artifact: 62aee611 user: drh) | |
| 00:29 | A simpler fix for ticket [3a88d85f36704eebe1] - one that uses less code. The error message is not quite as good, but as this error has apparently not previously occurred in over 8 years of heavy use, that is not seen as a serious problem. (check-in: 0ad1ed8e user: drh tags: trunk) | |

The following SQL script segfaults while running the INSERT statement: CREATE TABLE t1(x DEFAULT(max(1))); INSERT INTO t1(rowid) VALUES(1); The problem appears to be the use of an aggregate function as part of the default value for a column. This problem has been in the code since at least 2006-01-01 and probably before that. This problem was detected and reported on the sqlite-users@sqlite.org mailing list by Zsbán Ambrus. | ||||
