The xBestIndex method of the FTS5 virtual table misbehaves in the following input: <blockquote><verbatim> CREATE VIRTUAL TABLE ft USING fts5(x); SELECT * FROM ft WHERE ft.rowid IS NULL; </verbatim></blockquote> The above results in an error: "ft.xBestIndex malfunction". In other queries, this malfunction might result in memory leaks or even NULL pointer dereferences. | ||||
