    Description

      I'm running MariaDB in Docker on Windows. Running the following script crashes the server:

      drop table if exists t;
      		 
      create table t (i int, j int);
      		 
      insert into t values (1, 1), (2, 1), (3, 2), (4, 2);
      		 
       
      		 
      select 
        i, 
        max(i) over (partition by (select 1))
      		 
      from t
      		 
      order by i asc;
