When I do M-x slime-connect, I get an error in the SLIME debugger. I use a CLISP 2.45 pre-compiled binary on Windows XP SP3. Here is the error and backtrace: Winsock error 10038 (ENOTSOCK): Socket operation on non-socket [Condition of type SYSTEM::SIMPLE-OS-ERROR] Restarts: 0: [SOCKET-STATUS] Return from socket-status. 1: [ABORT] Abort 2: [CLOSE-CONNECTION] Close SLIME connection 3: [ABORT] Abort main loop Backtrace: 0: [292] frame binding variables (~ = dynamically): | ~ SWANK::*SWANK-STATE-STACK* <--> NIL 1: [289] frame binding variables (~ = dynamically): | ~ SWANK::*SLDB-STEPPING-P* <--> NIL 2: [286] frame binding variables (~ = dynamically): | ~ SWANK::*SLDB-LEVEL* <--> 0 3: [283] frame binding variables (~ = dynamically): | ~ *PACKAGE* <--> #<PACKAGE COMMON-LISP-USER> 4: <1/276> #<COMPILED-FUNCTION SWANK::DEBUG-IN-EMACS> -
