      Both debug and non-debug builds fail.

      On 10.0-10.2 (and on upstream 5.6, 5.7) there is no assertion failure, but the error looks strange:

      mysqltest: At line 5: query 'ALTER TABLE t1 ADD c SERIAL' failed: 1795: InnoDB presently supports one FULLTEXT index creation at a time

      Note that it happens upon adding the next column, not upon adding the second FULLTEXT index.

          On 10.0-10.2 (and on upstream 5.6, 5.7) there is no assertion failure, but the error looks strange:
