I've stripped my .emacs and .sbclrc right down and can still reproduce
the error if I follow the steps below

1. Start a fresh instance of emacs
2. M-x slime
3. Enter (some-undefined-function) into the repl

.emacs

(setq inferior-lisp-program "/usr/local/bin/sbcl")
(add-to-list 'load-path "/usr/src/slime/")  ; your SLIME directory
(require 'slime)
(slime-setup)

.sbclrc

(declaim (optimize (safety 3) (debug 3) (speed 0) (space 0)))

Cheers,
