crashing in innodb

Hi,

I built the 4.1.2 from source tree (latest as on today ) on my Redhat-8
box. While running,  mysqld 
crashes with the following set of queries:

CREATE TABLE tt1 (col1 int(1))ENGINE=InnoDB;
CREATE TABLE tt2 (col1 int(1),stamp TIMESTAMP,INDEX stamp_idx
(stamp))ENGINE=InnoDB;
insert into tt2 values (1, 20020204130000);
SELECT col1 FROM tt1 UNION SELECT col1 FROM tt2 WHERE stamp <
'20020204120000' GROUP BY col1;

These queries are there in the innodb test case of mysql-test suite
also. Because of this, even mysql-test suite 
fails to run the innodb test.


Following is the output:

040123 13:46:02  InnoDB: Started; log sequence number 0 83356
