I am not sure if I follow entirely. perhaps you can elaborate if I seem to have misunderstood. I think the following program just loads the :elephant system and then calls open-store. Is this what you mean?
(asdf:operate 'asdf:load-op :elephant) (let ((store-spec '(:BDB "store"))) (elephant:open-store store-spec)) This code causes a the same sort of SBCL disconnect (and exit code 256). Strangely I only see these errors in Slime. Since I am a lisp novice, I do not know much about how to debug these problems myself. thanks again, red daly P.S. I have also posted this problem on the slime-devel mailing list in case they have any insights/resolutions. On Thu, 2006-10-05 at 18:39 -0400, Ian Eslick wrote: > Could be some odd case in asdf.
