  1.2443 05/09/19 03:26:54 evgen@stripped +3 -0
  Fix bug #13180 thd->allow_sum_funcs wasn't reset before update.
  
  thd->allow_sum_func was left 'true' after previous statement thus allowing
  sum funcs to be present in conditions.
  
  Now thd->allow_sum_func is set to false in mysql_prepare_update().
