I am trying to use sbcl+slime on Windows (Emacs 23.2.1, Sbcl 1.0.37, Windows XP SP2 + cygwin 1.7.5, Slime just downloaded). When I happen to exit the debugger by selecting the "Exit debugger, returning to top level" restart, I get: Lisp connection closed unexpectedly: connection broken by remote peer. Any suggestion? For example, I entered the unbound symbol FOOBAR in the repl, and after the crash *slime-events* contains: ---------------------------------------------------------------- (:emacs-rex (swank:listener-eval "foobar\n") "COMMON-LISP-USER" :repl-thread 4) (:debug 0 1 ("The variable FOOBAR is unbound." " [Condition of type UNBOUND-VARIABLE]" nil) (("RETRY" "Retry SLIME REPL evaluation request.") ("ABORT" "Return to SLIME's top level.") ("CLOSE-CONNECTION" "Close SLIME connection") ("ABORT" "Exit debugger, returning to top level."))
