Description:
Trying to coalesce a table with only 11 records :-(

Errors are (from /home/ndbdev/jmiller/clones/mysql-5.1-new/mysql-test/var/log/mysqltest-time) :
mysqltest: At line 23: query 'ALTER TABLE test.t1 COALESCE PARTITION 4' failed: 1037: Out of memory; restart server and try again (needed 8 bytes)

How to repeat:
CREATE TABLE test.t1 (
  c1 MEDIUMINT NOT NULL AUTO_INCREMENT,
  c2 TEXT NOT NULL,
  c3 INT NOT NULL,
  c4 BIT NOT NULL,
  c5 FLOAT,
  c6 VARCHAR(255),
  c7 TIMESTAMP,
  PRIMARY KEY(c1,c3))
  ENGINE=NDB
  PARTITION BY KEY(c3) PARTITIONS 5;

let $j= 11;
--disable_query_log
while ($j)
{
  eval INSERT INTO test.t1 VALUES (NULL, "Tested Remotely from Texas, USA", $j, b'0',
                                   $j.00,"By JBM $j","2006-01-26");
  dec $j;
}
--enable_query_log
ALTER TABLE test.t1 COALESCE PARTITION 4;

DROP TABLE test.t1;
