Environment:Linux Redhat 7 (but running mariadb 10.3.27-MariaDB-log).
Get signal 11, Error Code: 2013. Lost connection to MySQL server during query when do the following. This does not happen on 10.3.17 nor on 10.3.23. This only errors if col_name is the primary key in the example below.
To reproduce do the following:
create table test_crash(col_name varchar(64), primary key (col_name)); #only fails if col_name is a primary key
#fails on .27, works on .17 and .23
select d.col_name
from information_schema.columns i
inner join test_crash d on d.col_name=i.column_name
group by d.col_name;
