      2016-10-19 11:26:05 7fc6502a6700 InnoDB: Assertion failure in thread 140489725208320 in file fts0que.cc line 3659
      InnoDB: Failing assertion: !query->intersection
      InnoDB: We intentionally generate a memory trap.
      InnoDB: Submit a detailed bug report to http://bugs.mysql.com.
      InnoDB: If you get repeated assertion failures or crashes, even
      InnoDB: immediately after the mysqld startup, there may be
      InnoDB: corruption in the InnoDB tablespace. Please refer to
      InnoDB: http://dev.mysql.com/doc/refman/5.6/en/forcing-innodb-recovery.html

      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.
      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.
      Please help us make Percona XtraDB Cluster better by reporting any
      bugs at https://bugs.launchpad.net/percona-xtradb-cluster

      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 57007 K bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      Thread pointer: 0x1b49590
      Attempting backtrace. You can use the following information to find out
      where mysqld died. If you see no messages after this, something went
      terribly wrong...
      stack_bottom = 7fc6502a5d38 thread_stack 0x40000

      Trying to get some variables.
      Some pointers may be invalid and cause the dump to abort.
      Query (7fc488060340): is an invalid pointer
      Connection ID (thread ID): 9196650
      Status: NOT_KILLED
