2020-07-16 15:44:50 0x7f9cd500f700 InnoDB: Assertion failure in thread 140311565235968 in file dict0dict.cc line 6322
InnoDB: We intentionally generate a memory trap.
InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
InnoDB: If you get repeated assertion failures or crashes, even
InnoDB: immediately after the mysqld startup, there may be
InnoDB: corruption in the InnoDB tablespace. Please refer to
InnoDB: http://dev.mysql.com/doc/refman/5.7/en/forcing-innodb-recovery.html
InnoDB: about forcing recovery.

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
Attempting to collect some information that could help diagnose the problem.
As this is a crash and something is definitely wrong, the information
collection process might fail.
Please help us make Percona Server better by reporting any
bugs at https://bugs.percona.com/key_buffer_size=1048576
read_buffer_size=131072
max_used_connections=1
max_threads=152
thread_count=1
connection_count=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 61255 K bytes of memory
Hope that's ok; if not, decrease some variables in the equation.Thread pointer: 0x7f9c74000e10
Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

Steps to reproduce:
CREATE TABLE t1 (f VARCHAR(256)) ENGINE=InnoDB;
SET SESSION FOREIGN_KEY_CHECKS = OFF;
ALTER TABLE t1 ADD FOREIGN KEY (f) REFERENCES non_existing_table (x);
SET SESSION FOREIGN_KEY_CHECKS = ON;
ALTER TABLE t1 ADD FULLTEXT INDEX ft1 (f);
ALTER TABLE t1 ADD FULLTEXT INDEX ft2 (f);
DROP TABLE t1;
