In function fts5VocabDisconnectMethod and fts5VocabDestroyMethod in /ext/fts5/fts5_vocab.c, there is a memory leak. Field *zFts5Tbl, *zFts5Db, *db should be freed before statement sqlite3_free(pTab);.

struct Fts5VocabTable {
  sqlite3_vtab base;
  char *zFts5Tbl;                 /* Name of fts5 table */
  char *zFts5Db;                  /* Db containing fts5 table */
  sqlite3 *db;                    /* Database handle */
  Fts5Global *pGlobal;            /* FTS5 global object for this database */
  int eType;                      /* FTS5_VOCAB_COL, ROW or INSTANCE */
};

static int fts5VocabDisconnectMethod(sqlite3_vtab *pVtab){
  Fts5VocabTable *pTab = (Fts5VocabTable*)pVtab;
  sqlite3_free(pTab);
  return SQLITE_OK;
}

static int fts5VocabDestroyMethod(sqlite3_vtab *pVtab){
