Minimal repro, seems like something is going wrong when one of the tokens in the fulltext index is too long.

create table t (
  i int unsigned,
  t1 varchar(255),
  t2 mediumtext,
  unique key(i),
  fulltext key (t1),
  fulltext key (t2)
);

insert into t values (0, 'abc', 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa');
replace into t values (0, 'abc', 'aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa');

There are 90 a's

This looks like an unchecked internal limit on the size of each token for fulltext indexes.
