should relate to bug#19022: Memory bug when switching db during trigger execution. My conclusion is based on observation of #20579 fails on by 0x617C73: mysql_insert(THD*, st_table_list*, List<Item>&, List<List<Item> >&, List<Item>&, List<Item>&, enum_duplicates, bool) (sql_insert.cc:570) which is the following, not the preceeding!, to #19022's failing line: by 0x5F859F: mysql_insert(THD*, st_table_list*, List<Item>&, List<List<Item> >&, List<Item>&, List<Item>&, enum_duplicates, bool) (sql_insert.cc:569) I assume we are better to check the case with #19022 fix first.
