test case:

CREATE TABLE t1 ( f1 date, KEY (f1)) ;
INSERT IGNORE INTO t1 VALUES (NULL),(NULL);

SELECT * FROM t1 WHERE f1 = FROM_UNIXTIME( 2002190336 , "%m''%w''%d''%c''%T" );

Re: Assertion `(was_cut & 1) == 0' failed in Field_temporal::store_TIME_with_warning() in 5.1-micro
Also repeatable with a more realistic format:

FROM_UNIXTIME( 2002190336 , CONCAT_WS( ':' , '%m' , '%w' , '%d' , '%c' , '%T' ) )
