Description

The following example causes my mysqld process to crash and restart:

create table t1 (id int(11) not null auto_increment, val varchar(100) null,primary key (id)) engine=innodb;

create table t2 (id int(11) not null auto_increment, val varchar(100) null,primary key (id)) engine=innodb;

insert into t1 (val) values('a');

insert into t2 (val) values('1');

update

        select

val

        from

                select

                    v.val

                from

                    t2 wrong_table_alias

            ) t4

    ) t3

    inner join t1 on

        t1.id=t3.val

set

    t1.val=t3.val

will cause the client to report:
ERROR 2013 (HY000): Lost connection to MySQL server during query

with the following appearing in the mysql-error.log

Server version: 5.5.32-MariaDB-log

key_buffer_size=134217728

read_buffer_size=131072

max_used_connections=2

max_threads=502

thread_count=1

It is possible that mysqld could use up to

key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 1232371 K  bytes of memory

Hope that's ok; if not, decrease some variables in the equation.

I realized that I attached the mysql-error.log from a 5.5.32 server, but it also still affects a 5.5.33a server. Here is the log from that server
131015 13:51:28 [ERROR] mysqld got signal 11 ;
This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.

To report this bug, see http://kb.askmonty.org/en/reporting-bugs

We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed,
something is definitely wrong and this may fail.

it is just wrong query which crashes before error is returned... So it should be fixed.

The problem is that mysql_derived_prepare do not check result of sl->handle_derived() call.
