"wrong-number-of-arguments (2 . 4) 5" on startup

[esquivalient]

I tried to set up what I think is the simplest version of chemacs to play around with it. When I execute

emacs --debug-init --with-profile spacemacs

with the following as my .emacs-profiles.el

(("default" . ((user-emacs-directory . "~/.emacs.d")))
 ("spacemacs" . ((user-emacs-directory . "~/code/emacs/spacemacs/"))))

I get the error in the title (full trace at the bottom of this issue). I'm not well versed in elisp or reading its stack traces, so there's probably something obvious that I'm missing.

Try replace the function chemacs-get-emacs-profile with

(defun chemacs-get-emacs-profile (profile)
  (assoc profile chemacs-emacs-profiles))

After that, it works for me with .emacs-profiles.el

(
 ("default" . ((user-emacs-directory . "~/.emacs.d")))
 ("spacemacs-dev" . ((user-emacs-directory . "~/.test.d/")))
)

alist-get got an extra optional TEST-FN argument in Emacs 24.5 (I think, looking at the commit history).

assoc is not the same, since it returns the association pair, instead of just the value.

I'll push a fix for older Emacsen.

Thanks for reporting, it should be fixed on master now. Please give it a go!
