Description:
Noticed when handling bug: http://bugs.mysql.com/bug.php?id=58449.
Loading the ha_innodb_plugin.dll release built with the debug server crash it:

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.
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.
key_buffer_size=8384512
read_buffer_size=131072
max_used_connections=1
max_threads=151
threads_connected=1
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 338138 K
bytes of memory
Hope that's ok; if not, decrease some variables in the equation.

Attempting backtrace. You can use the following information to find out
where mysqld died. If you see no messages after this, something went
terribly wrong...

How to repeat:
CREATE TABLE `debug`.`A` (
`a_id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`a_content` VARCHAR( 100 ) NOT NULL
) ENGINE = INNODB;
# Create table B
CREATE TABLE `debug`.`B` (
`b_id` INT NOT NULL AUTO_INCREMENT PRIMARY KEY ,
`a_id` INT NOT NULL ,
`b_content` VARCHAR( 100 ) NOT NULL ,
INDEX ( `a_id` )
) ENGINE = INNODB;
# Add FK to B
ALTER TABLE `B` ADD FOREIGN KEY ( `a_id` ) REFERENCES `debug`.`A` (`a_id`)
ON DELETE CASCADE ON UPDATE CASCADE;
