      Description

      All nodes excepted for the one on which query was executed will crash if DDL with function was executed.

      Steps to reproduce:
      1. Execute:

      ALTER USER USER() IDENTIFIED BY 'the infinite improbability drive';
      

      2. All nodes excepted the one on which the query was execute will crash with the following stack trace:

      09:10:16 UTC - 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.
      Attempting to collect some information that could help diagnose the problem.
      As this is a crash and something is definitely wrong, the information
      collection process might fail.
      Please help us make Percona XtraDB Cluster better by reporting any
      bugs at https://jira.percona.com/projects/PXC/issues
      
      key_buffer_size=8388608

      max_used_connections=0
      max_threads=152
      thread_count=3
      connection_count=0
      It is possible that mysqld could use up to 
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 68412 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
