How to repeat:
1. on master create a table:
create table `t1` (`a` int(11) not null auto_increment,
`col001` bigint unsigned default null, primary key (`a`)
) engine=myisam default charset=latin1;
2. on slave create a table:
create table `t1` ( `a` int(11) not null auto_increment,
`col001` bigint not null, primary key (`a`)
) engine=myisam default charset=latin1;
3. setup replication correctly, using binlog_format=row
4. on master, execute this:
insert ignore into `t1` set `col001`=null;
observe either a crash (perhaps after many inserts, or immediate valgrind errors).
Suggested fix:
do the conversion correctly.
