mysqld: sql_class.cc:411: void Diagnostics_area::set_ok_status(THD*, ha_rows, ulonglong, const char*): Assertion `! is_set()' failed.

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=1048576000
read_buffer_size=4194304
max_used_connections=3
max_threads=300
threads_connected=0
It is possible that mysqld could use up to
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 21916646 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...

The manual page at http://dev.mysql.com/doc/mysql/en/crashing.html contains
information that should help you find out what is causing the crash.
How to repeat:
Set up four servers:
1) Master
2) Slave
3) Kang
4) Kodos
Create two tables on Kang and Kodos called ProductInstance and RetailerInventory of MyISAM table type. Create options for each are:
ENGINE=MyISAM DEFAULT CHARSET=utf8 MAX_ROWS=2431504384 AVG_ROW_LENGTH=50 ROW_FORMAT=DYNAMIC
On Master create ProductInstance and RetailerInventory FEDERATED tables which reference its counterparts on Kodos.
Create on Master ProductInstance_kang and RetailerInventory_kang which reference counterparts on Kang.
Execute on Master:
RENAME TABLE RetailerInventory TO RetailerInventory_kodos, RetailerInventory_kang TO RetailerInventory
Query completes successfully on master. On slave causes the assertion failure in description.
We actually have two slave servers which both assert-fail on this statement.
Suggested fix:
Figure out why the assertion condition is failing and fix the underlying problem. ;)
