This is reproducible everytime. Doing a CREATE from SELECT, and then adding INDEX on column results in crashing of all other servers in Galera cluster.

I have attached my.cnf MariaDB configuration, and the test setup is simple consiting of three servers. Execute this on one of the servers:

CREATE DATABASE foobar;

USE foobar;

CREATE TABLE foo (

  timestamp int(11) NOT NULL DEFAULT '0'

) ENGINE=InnoDB DEFAULT CHARSET=utf8;

INSERT INTO foo (timestamp) VALUES (1), (2), (3);

CREATE TABLE bar (timestamp INT) SELECT timestamp FROM foo; ALTER TABLE bar ADD INDEX tind (timestamp);

And all the rest of the servers will crash. I have attached relevant log files. Take a look at server.2.log or server.3.log.

Some widely used software (ie Drupal's Views Data Export module) uses this statements, which is how we encountered this bug.
