I'm not quite sure I understand this bug report.  First of all,
`org-fc-with-point-at-back-heading' doesn't seem to exist in the Emacs
tree, so is this from an external package?

The other issue is that I think there's a misunderstanding here: You can
never funcall a macro.

(macrop 'when)
=> t
(fboundp 'when)
=> t
(funcall 'when)
=> Debugger entered--Lisp error: (invalid-function when)
    when()

Macros are foundp, but that doesn't mean you can funcall them.
