      Description

      Looks like almost same crash location as MDEV-21415, though there are differences. May be related.

      USE test;
      SET tmp_table_size=1024;
      SET tmp_disk_table_size=1024;
      CREATE TABLE t1 (x INT(11), row_start BIGINT(20) UNSIGNED GENERATED ALWAYS AS ROW START INVISIBLE, row_end BIGINT(20) UNSIGNED GENERATED ALWAYS AS ROW END INVISIBLE, PERIOD FOR SYSTEM_TIME (row_start, row_end)) WITH SYSTEM VERSIONING;
      INSERT INTO t1 VALUES(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1),(1);
      SELECT * FROM t1 INTERSECT ALL SELECT * FROM t1 INTERSECT ALL SELECT * FROM t1;
      

      Leads to:
