Starting in late September, whenever I try to exit out of the debugger the repl prompt doesn't come back. Example: *slime-repl sbcl* CL-USER> o *sldb sbcl/0* The variable O is unbound. [Condition of type UNBOUND-VARIABLE] Restarts: 0: [RETRY] Retry SLIME REPL evaluation request. 1: [ABORT] Return to SLIME's top level. <-----------pick this one 2: [CLOSE-CONNECTION] Close SLIME connection 3: [ABORT] Exit debugger, returning to top level. The repl buffer comes back with no prompt, and all further requests are pipelined. This does not happen in clisp. Some other info: *slime-events* (:emacs-rex (swank:listener-eval "o\n") "COMMON-LISP-USER" :repl-thread 14) (:debug 0 1 ("The variable O 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."))
