Stefan, can you help maybe?  Gabriele then does this:

#+begin_src emacs-lisp
(advice-add 're-search-forward-ifpmod
            :around
            #'make-search-sensitive-to-ifpmod-advice)
#+end_src

and we have found that this causes weird errors because at least some
definitions, like `forward-paragraph', call `re-search-forward-ifpmod'
afterwards.  This seems to happen only when using a native compiled
Emacs, and the effect disappears when loading the source - paragraphs.el
in this case.  Is this normal?
