Mmm... I run org-lint (and fix unrelated issues, thanks!) and the problem 
remains.
It is strange though, this is the block on which the function
stops working (it is the first actually)

   #+begin_src emacs-lisp :tangle yes
   (defun my/init-audit-message (string)
     "Print out STRING and calculate length of init."
     (message string)
     (if (not (string= "end" (substring string -3)))
         (setq my/init-audit-message-begin (current-time))
       (message
        "It took %s seconds in total."
        (time-to-seconds
         (time-subtract
          (current-time)
          my/init-audit-message-begin))))
     nil)
   #+end_src

Must be something wrong with my configuration then.
I will update this issue if I find that out.
