# This bug is the result of merging the Oracle MySQL follow-up fix
# BUG#22963169 MYSQL CRASHES ON CREATE FULLTEXT INDEX
# without merging a fix of Bug#79475 Insert a token of 84 4-bytes
# chars into fts index causes server crash.

# Oracle did not publish tests for either of the above MySQL bugs.
# The tests below were developed for MariaDB Server.
# The maximum length of a fulltext-indexed word is 84 characters.
