This is the minimal init.el:

------------------------------------------------------------
$ cat init.el
(setq default-frame-alist
      '(
        (width . 110) ; character
        (height . 56) ; lines
        ))

;; Adds the MELPA repo to Emacs Packages
(when (>= emacs-major-version 24)
  (require 'package)
  (add-to-list
   'package-archives
   '("melpa" . "http://melpa.org/packages/")
   t)
  ;;(package-initialize)
  )


;; Sr-speedbar startup
(defun start-sr-speedbar ()
  "My customization for `sr-speedbar' startup."
  (interactive)

  ;; Start sr-speedbar at Emacs startup
  (sr-speedbar-open)

  ;; As suggested here:
  ;;
  ;;   http://lists.gnu.org/archive/html/bug-gnu-emacs/2017-07/msg01125.html
  ;;
  ;; (Really I had tried this solution but putting it in wrong place!)
  ;;
  (ad-deactivate 'pop-to-buffer)
  )

;; Start sr-speedbar, as suggested here:
;;
;;   http://lists.gnu.org/archive/html/bug-gnu-emacs/\
;;     2017-04/msg00569.html
;;
;;(add-hook 'emacs-startup-hook 'start-sr-speedbar) ; the old way
(add-hook 'window-setup-hook 'start-sr-speedbar)

;; Setup sr-speedbar
(setq sr-speedbar-default-width 30)
(setq sr-speedbar-width 30)
(setq sr-speedbar-max-width 30)
(setq sr-speedbar-auto-refresh t)

------------------------------------------------------------

I notice that with that init file, now Emacs starts with a double scratch buffer (one in text window and one in sr-speedbar window) and minibuffer contains "Opening directory: No such file or directory, c:/msys2/tmp/emacs-master/src/". Indeed I removed the directory: c:/msys2/tmp/emacs-master. It is the directory where the Emacs source is expanded (I use the emacs-master.tar.gz from git repo).

I notice also that Buffer menu contains *Compile-Log* buffer with the text:

Compiling no file at Wed Dec  5 00:20:12 2018

and *Messages* buffer has text:

For information about GNU Emacs and the GNU system, type C-h C-a.
‘sr-speedbar’ window has exist.
speedbar-file-lists: Opening directory: No such file or directory, c:/msys64/tmp/emacs-master/src/

Whwn I use the previous build (Oct 31) with the same init.el, Emacs starts with the *GNU Emacs* buffer (the same of Help - About Emacs menu) and the minibuffer contains "For information about[...]", as expected.
