          Description

          The root cause of the problem might exist in 5.5 and 10.0 too, but I am not getting a crash there, no valgrind errors either, and query results seem to be reasonable (shown at the end of the description).

          CREATE TABLE t1 (i INT, d DATE) ENGINE=MyISAM;
INSERT INTO t1 VALUES (1, '2008-10-02'), (2, '2010-12-12');
SELECT d, AVG( EXPORT_SET( 13, 'Y', ( SHA( i ) ) ) ), GROUP_CONCAT( d ) 
FROM t1 GROUP BY d ORDER BY i;

          Stack trace on 5.3 (although not very helpful):

revno: 3635
branch-nick: 5.3

          Reproducible on older revisions, too.

          Built with BUILD/compile-pentium-valgrind-max-no-ndb; was also reproducible with BUILD/compile-pentium-debug-max-no-ndb.
          I tried 3 different machines, 2 Ubuntus and Gentoo, got the crash on each of them.

          Results on 5.5 (I don't see a problem here):

          INSERT INTO t1 VALUES (1, '2008-10-02'), (2, '2010-12-12');
SELECT d, AVG( EXPORT_SET( 13, 'Y', ( SHA( i ) ) ) ), GROUP_CONCAT( d ) 
FROM t1 GROUP BY d ORDER BY i;
d	AVG( EXPORT_SET( 13, 'Y', ( SHA( i ) ) ) )	GROUP_CONCAT( d )
2008-10-02	0	2008-10-02
2010-12-12	0	2010-12-12
