      How to reproduce manually

      # Start cluster (1 node is enough, or it can be more)
      # connect to a node
      # run 
      USE test;
      DROP TABLE IF EXISTS t1;
      CREATE TABLE t1 AS SELECT SLEEP(30);
       
      # while the last statement is running, open another connection to the same node and run
      DROP TABLE IF EXISTS test.t1;
       
      # Observe the crash

      MTR test case

      # Run as
      # perl --mysqld=--wsrep_provider=/home/elenst/galera-23.2.1-src/libgalera_smm.so --mysqld=--binlog-format=row --mysqld=--innodb --mysqld=--default-storage-engine=InnoDB --mysqld=--innodb_autoinc_lock_mode=2 --mysqld=--innodb_locks_unsafe_for_binlog=1 --mysqld=--innodb_flush_log_at_trx_commit=0 --mysqld=--wsrep_cluster_address=gcomm:// ./mtr main.t1 
       
      DROP TABLE IF EXISTS t1;
      --send CREATE TABLE t1 AS SELECT SLEEP(3)
      --sleep 1
      --connect (con1,localhost,root,,)
      DROP TABLE IF EXISTS t1;
      --connection default
      --reap

      Shell script

      #!/bin/bash
       
      port=${1:-3306}
      client=${2:-mysql}
       
      $client --no-defaults -uroot --protocol=tcp --port=$port -e "DROP TABLE IF EXISTS test.t1"
      $client --no-defaults -uroot --protocol=tcp --port=$port -e "CREATE TABLE test.t1 AS SELECT SLEEP(5)" &
      sleep 1
      $client --no-defaults -uroot --protocol=tcp --port=$port -e "DROP TABLE IF EXISTS test.t1"
       
      fg
      $client --no-defaults -uroot --protocol=tcp --port=$port -e "SHOW STATUS LIKE 'wsrep%'"
       

      My server command line
