insert delayed statements into a table where the specified column didn't exist, causes a crash.  Stack trace:

On windows 5.1.23:


On linux, I saw this assertion:

Version: '5.1.23-rc-debug-log'  socket: '/tmp/mysql.sock'  port: 3306  yes
safe_mutex: Trying to lock unitialized mutex at sql_insert.cc, line 2181
071123 19:42:51 - mysqld got signal 6;

How to repeat:
#server must be started cleanly.

flush tables;
drop table if exists `t`;
create table `t` (`a` int)engine=myisam;
insert delayed into `t` set `b`=b();

Noted in 5.0.54, 5.1.23, 6.0.5 changelogs.

Specifying a non-existent column for an INSERT DELAYED statement 
caused a server crash rather than producing an error.
