Verified by code review. Actually, 5.1-bzr has the same code, line 381.

At e:\builds\bzr\6.0\storage\myisammrg\ha_myisammrg.cc:528 /* Extract the MyISAM table structure pointer from the handler object. */ if ((child->file->ht->db_type != DB_TYPE_MYISAM) || !(myisam= ((ha_myisam*) child->file)->file_ptr())) { DBUG_PRINT("error", ("no MyISAM handle for child table: '%s'.'%s' %p", child->s->db.str, child->s->table_name.str, child)); my_errno= HA_ERR_WRONG_MRG_TABLE_DEF; } DBUG_PRINT("myrg", ("MyISAM handle: %p my_errno: %d", myisam, my_errno)); <--------- HERE How to repeat: please review the code and see that "myisam" is not given a value if child->file->ht->db_type != DB_TYPE_MYISAM.
