I think the problem is here (in read_key_sequence):

  /* If there is no translation-map, turn off scanning.  */
  fkey.start = fkey.end = KEYMAPP (fkey.map) ? 0 : bufsize + 1;
  keytran.start = keytran.end = KEYMAPP (keytran.map) ? 0 : bufsize + 1;

If function-key-map is nil but key-translation-map is not then further
down uninitialised values of keybuf are scanned (fkey.start = 31):

      ...
      /* Look for this sequence in key-translation-map.
         Scan from keytran.end until we find a bound suffix.  */
      while (keytran.end < fkey.start)
      ...
