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

|
max_used_connections=5
|

|
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;

It seems that several dynamic strings in replication cause the crash.
replicate_do_db, replicate_do_table, replicate_ignore_db, replicate_ignore_table, replicate_wild_ignore_table, replicate_wild_do_table
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.
