If sqlite3_column_value() is called to obtain a value with the MEM_Static flag set, clear it and set the MEM_Ephem flag before returning. Otherwise, if the value is passed to sqlite3_bind_value() or sqlite3_result_value(), sqlite may attempt to use the buffer after the statement has been finalized. This is not always valid, as MEM_Static only guarantees that a MEM.z buffer will be valid for the lifetime of the owner statement, not that it is actually a static buffer. (CVS 5812)
