The following SQL statement causes a crash due to attempt to free memory that was not obtained from malloc(): <blockquote><verbatim> SELECT +sum(0)OVER() ORDER BY +sum(0)OVER(); </verbatim></blockquote> This problem has existed in all prior versions of SQLite that support window functions, beginning with version 3.25.0 (2018-09-15). | ||||
