          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.

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...

          The following works as expected:

SET GLOBAL replicate_wild_ignore_table = "";
START SLAVE;

                Thanks for the report.

                Reproducible on old versions of 5.5 as well.
                Not reproducible on MySQL because there it's not a variable, just a command-line option.
