      Description

      When trying to clear list of wildcards:

      STOP SLAVE;
      SET GLOBAL replicate_wild_ignore_table = null;
      START SLAVE;

      MariaDB crashes, following from logs:

      50617 23:55:37 [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: 10.0.19-MariaDB-log
      key_buffer_size=67108864
      read_buffer_size=4194304
      max_used_connections=5
      max_threads=202
      thread_count=3
      It is possible that mysqld could use up to
      key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 14135174 K  bytes of memory
      Hope that's ok; if not, decrease some variables in the equation.

      The following works as expected:

      STOP SLAVE;
      SET GLOBAL replicate_wild_ignore_table = "";
      START SLAVE;
