synth_mult in expmed.c has a condition that checks the mode member twice:

  /* See if we already know what to do for T.  */
  entry_ptr = alg_hash_entry_ptr (hash_index);
  if (entry_ptr->t == t
      && entry_ptr->mode == mode
      && entry_ptr->mode == mode
      && entry_ptr->speed == speed
      && entry_ptr->alg != alg_unknown)
