    Description

      I tried this syntax with SPIDER, because it is supported with FederatedX. It crashes the server. (this problem does not occur with CONNECT)

      MariaDB [test]> CREATE OR REPLACE TABLE user
          -> ENGINE = SPIDER
          -> COMMENT 'host "127.0.0.1", user "root", password "root", database "db1", table "user"';
      ERROR 2013 (HY000): Lost connection to MySQL server during query

      Errlog:

      Error formatting macro: code: java.lang.StackOverflowError

      140526 4:10:33 [ERROR] mysqld got signal 11 ;
      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.

      To report this bug, see http://kb.askmonty.org/en/reporting-bugs

      We will try our best to scrape up some info that will hopefully help
      diagnose the problem, but since we have already crashed,
      something is definitely wrong and this may fail.

      Server version: 10.0.11-MariaDB-log
      key_buffer_size=134217728
      read_buffer_size=131072
      max_used_connections=1
      max_threads=501
      thread_count=2
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1224392 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      where mysqld died. If you see no messages after this, something went
      terribly wrong...
