ChangeSet@1.2543, 2007-06-30 18:02:38+10:00, stewart@flamingspork.com +1 -0   [PATCH] BUG#27404 util thd mysql_parse sig11 when mysqld default multibyte charset   

  NDB util thread calls mysql_parse internally with plain old c strings (7bit ascii) to create tables (e.g. mysql.ndb_schema). With mysqld default charset set to a multibyte one (e.g. ucs2) mysql_parse would try to interpret the 7bit string as UCS2 and promptly explode in a heap.   

  Solution is to set the util thread to be using utf8 charset.
