I also encountered this problem in a normal situation; to reproduce:

1) Download http://www.logic.at/prolog/ediprolog/ediprolog.el
   and install SWI-Prolog from www.swi-prolog.org .

2) $ emacs -Q -nw -f server-start

3) $ emacsclient -c ediprolog.el
   M-x eval-buffer

4) In the *scratch* buffer, insert on a separate line:

   ?- X is 7^7^7.

   and do M-x ediprolog-dwim with point on that line. While the quite
   large number is inserted in the buffer (it takes a while), press C-g
   a few times, until the server suspends.
