Server crash when dynamic replication strings are set to NULL

    Details

      Description

      With the statement 'SET GLOBAL replicate_do_db=NULL', the server crashes with the following backtrace:

      161013  9:08:50 [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 https://mariadb.com/kb/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: 10.1.14-MariaDB
      key_buffer_size=33554432
      read_buffer_size=262144
      max_used_connections=6
      max_threads=1001
      thread_count=1
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 805576 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.
