Build of 5.0.4, based on ChangeSet
  1.1889 05/04/08 16:49:14 mskold@mysql.com +4 -0
  Merge from fix of Bug #9675  Auto-increment not working with INSERT..SELECT
and NDB storage

This bug seems specific to "s390", as the symptom differs from bug#9826 (HP-UX, 32 bit):
=== quote start ===
ndb_alter_table                [ fail ]

Errors are (from /xspace/mysqldev/etpglb0/test/mysql-cluster-5.0.4-beta-ibm-linux-gnu-s390/mysql-test/var/log/mysqltest-time) :
/xspace/mysqldev/etpglb0/test/mysql-cluster-5.0.4-beta-ibm-linux-gnu-s390/bin/mysqltest: At line 20: query 'ALTER TABLE t1 ADD COLUMN c int not null' failed: 2013: Lost connection to MySQL server during query
(the last lines may be the most important ones)

Ending Tests
=== quote end ===

Subsequent NDB tests also fail, and soon the suite aborts.

How to repeat:
Build + test there.
