Comment 3 for bug 1657941

Crashes mysql for both debug and release builds.
Looks similar to http://bugs.mysql.com/bug.php?id=76418

--source include/have_innodb.inc

drop table if exists t;
create table t(id int(11) unsigned not null auto_increment, dttm datetime not null default current_timestamp, msg text,primary key (id,dttm)) engine=innodb default charset=utf8mb4 row_format=dynamic partition by range columns(dttm) (partition pf_201612 values less than ('20170101') engine = innodb);

select * from t where dttm > '2017-01-19' order by id desc;
