"slime-cl-indent-test.txt" was opened for no reason

Hello and sorry for my poor English.

When I start emacs, I sometimes see the slime-cl-indent-test.txt buffer.

I don't know why. Is it my configuration error?

Here is my slime configuration (Many of code comes from purcell/emacs.d):

(require-package 'slime)
(require-package 'hippie-expand-slime)

(add-hook 'lisp-mode-hook 'slime-mode)

(setq slime-contribs '(slime-repl slime-fuzzy))
(setq slime-net-coding-system 'utf-8-unix)
(setq slime-complete-symbol*-fancy t)
(setq slime-complete-symbol-function 'slime-fuzzy-complete-symbol)

(add-hook 'slime-mode-hook 'set-up-slime-hippie-expand)

;; REPL
(defun remx/slime-repl-setup ()
  "Mode setup function for SLIME REPL."
  (enable-paredit-mode)
  (indent-guide-mode -1)
  (aggressive-indent-mode)
  (set-up-slime-hippie-expand)
  (setq show-trailing-whitespace nil))

(with-eval-after-load 'slime-repl
  ;; Stop SLIME's REPL from grabbing DEL, which is annoying when backspacing over a '('
  (with-eval-after-load 'paredit
    (define-key slime-repl-mode-map (read-kbd-macro paredit-backward-delete-key) nil))
  ;; Bind TAB to `indent-for-tab-command', as in regular SLIME buffers
  (define-key slime-repl-mode-map (kbd "TAB") 'indent-for-tab-command)

  (add-hook 'slime-repl-mode-hook 'remx/slime-repl-setup))

;; Set lisp implementations
(with-eval-after-load 'slime
  (when (executable-find "sbcl")
    (add-to-list 'slime-lisp-implementations
                 '(sbcl ("sbcl") :coding-system utf-8-unix)))
  (when (executable-find "lisp")
    (add-to-list 'slime-lisp-implementations
                 '(cmucl ("lisp") :coding-system iso-latin-1-unix)))
  (when (executable-find "ccl")
    (add-to-list 'slime-lisp-implementations
                 '(ccl ("ccl") :coding-system utf-8-unix))))

(when (maybe-require-package 'slime-company)
  (add-to-list 'slime-contribs 'slime-company t))

Thank you.
