I don't know what happened to your first message, but this problem
seems to be fixed in the current CVS sources:

  octave:1> function x;y=;endfunction
  parse error:

  >>> function x;y=;endfunction
                   ^

  octave:1> function x;y=;endfunction
  parse error:

  >>> function x;y=;endfunction
                   ^

And so on, without a panic.
