          ALTER TABLE t drop index fidx, add fulltext index(c2);
          		 
          DROP TABLE t;

          Alternative test case to ignore PACK_KEYS. It fails in 10.2 as well

          Thanks, the logic looks OK to me. I only had some suggestions about formatting and comments.

          I think that it is best for mleich to test this, just in case.

          The RQG testing with the battery for broad range coverage on
          origin/bb-10.2-MDEV-22811 be5a2ef34358e6f8f0780eb45539ce991b6e2056 2020-06-15T15:49:47+05:30
          did not show new unknown crashes.
          Also the fraction of failing tests was ok.
