I do not understand your reply but AFAIU, the error shows up because the
compiler does not know about the pcase map matching pattern during
compilation-time so I think the problem is in org-bookmark-heading
package missing a require statement for map.el and not in core.
[ Akira proposes to autoload the map.el matching pattern to avoid future
  errors as rx's pattern is already autoloaded.  ]
