Howdy,

If you fire up SLIME in OpenMCL and pull up SLDB (e.g. with (/ 1 0)) then it seems the ABORT restart ('a') doesn't work. Invoking it seems to just return nil instead of aborting the evaluation.

Anyone know what's up?

I had to do an update from CVS and rebuild and restart Emacs. I have no idea how to debug this, but here is what I have observed with Activity Monitor. When SLIME is started the openmcl process is known as dppccl. It starts with 6 (six!) threads. It runs with 3 threads initially when started from bash. After trying (/ 1 0) and trying anything to get out of the debugger, I end up with just 5 threads. The REPL no longer gets any more prompts although I did get an evaluation aborted message. The *inferior-lisp* buffer is still active and still working. Here are my buffers. I had no idea *slime-events* was folded when I copied it. Sorry. Just trying to give out info to the people who know what all this voodoo means. *slime-repl* ; SLIME 2004-05-01 CL-USER> (/ 1 0) Invoking restart: #<RESTART ABORT #x41354E36> ; Evaluation aborted *slime-events* (:emacs-rex (swank:connection-info) nil t (lambda (&rest --cl-rest--) (apply (lambda (G100092 G100083) (let* ((tmp-100089 G100083) (op-100087 (car tmp-100089)) (rand-100088 (cdr tmp-100089))) (cond ((eql op-100087 ':ok) (let* ((--rest--100090 rand-100088) (result (if (= (length --rest--100090) 1) (car --rest--100090) (signal 'wrong-number-of-arguments (list nil (length --rest--100090)))))) (funcall (symbol-value G100092) result))) ((eql op-100087 ':abort) (let* ((--rest--100091 rand-100088)) (if --rest--100091 (signal 'wrong-number-of-arguments (list nil (+ 0 (length --rest--100091))))) (message "Evaluation aborted.")))
