      Description

      Test case:

      START TRANSACTION WITH CONSISTENT SNAPSHOT;
      SAVEPOINT A;

      It can be executed as an MTR test case, no options needed: perl ./mtr <testname>
      Or, I start the server as

      maria-5.5-galera/sql/mysqld --no-defaults --basedir=maria-5.5-galera --datadir=maria-5.5-galera/data1 --log-error=maria-5.5-galera/data1/log.err --loose-lc-messages-dir=maria-5.5-galera/sql/share --loose-language=maria-5.5-galera/sql/share/english --port=3306 --socket=maria-5.5-galera/data1/tmp/mysql.sock --tmpdir=maria-5.5-galera/data1/tmp --core

      same result.
