Description:
CREATE TABLE t1 ( f1 INTEGER, f2 char(20)) ENGINE = 'MYISAM'
PARTITION BY HASH(f1) PARTITIONS 2;

INSERT INTO t1 SET f1 = 0 , f2 = '#######';
--> harmless

INSERT INTO t1 SET f1 = 0 - 1   , f2 = '#######';
--> crash

A table with one partition
    CREATE TABLE t1 ( f1 INTEGER, f2 char(20)) ENGINE = 'MYISAM';
or
    INSERT INTO t1 SET f1 = 0 , f2 = '#######';
are harmless.

My environment:
   - Intel PC with Linux(SuSE 9.3)
   - MySQL compiled from source
