Version:	5.5.24	OS:	Microsoft Windows (7)
Assigned to:		CPU Architecture:	Any

Description:
Selecting WHERE partitionkey = NULL in the table below crashes mysqld.

How to repeat:
CREATE TABLE foo
( id INTEGER NOT NULL,  
  id1 INTEGER DEFAULT NULL,
  INDEX(id)
) ENGINE=InnoDB
  PARTITION BY LIST(MOD(id1, 2)) (
  PARTITION p00 VALUES IN (0),
  PARTITION p01 VALUES IN (1),
  PARTITION p03 VALUES IN (NULL)); 
  
SELECT id FROM foo WHERE id = 1 AND id1 = NULL;

Could you please try latest version 5.5.29. Thanks.

Thanks, I just tried on the latest version (5.5.29) & the query went through.
Mea culpa, I should have done it before submitting the bug.

this has been fixed since 5.5.27 or so.
