xterm.c:handle_one_xevent question

[Miles Bader]

I got an emacs abort at the following place in handle_one_xevent
(xterm.c):

        ...
          /* If not using XIM/XIC, and a compose sequence is in progress,
             we break here.  Otherwise, chars_matched is always 0.  */
          if (compose_status.chars_matched > 0 && nbytes == 0)
            break;

          orig_keysym = keysym;

          if (numchars > 1)
            {
              Lisp_Object c;

              /* First deal with keysyms which have defined
                 translations to characters.  */
              if (keysym >= 32 && keysym < 128)
                ...
              else
                abort ();
            }
          else
====>       abort ();
        ...


I don't understand this code; can someone explain why numchars has to
be > 1?  I've attached a bit of a gdb session, though it probably isn't
very helpful...

Thanks,
