Strange.  I guess the next step is to look at what Emacs receives from
aspell.  I think if you display the value of ispell-filter in
ispell-process-line, it will show that.  Here's the relevant part of
ispell-process-line:

    ;; send string to spell process and get input.
    (ispell-send-string string)
    (while (progn
	     (ispell-accept-output)
	     ;; Last item of output contains a blank line. <<<<<<<<<<<<
	     (not (string= "" (car ispell-filter)))))

Insert

    (message "%s" ispell-filter)

before the marked line, then load ispell.el manually, and repeat the
experiment.  The results should be in the *Messages* buffer.  Maybe if
we see what Emacs gets back from aspell, we will see the light.

Thanks.
