--- Comment #3 from Patrick Pelissier <patrick.pelissier at gmail dot com> ---
I have tested with GCC 7.1.0 the code of #0 (forget the function h, this was
only a reference) and the status is the same as described in #0.

For the following code,

int (*apply (int (*f) (const void *, const void *), void *a))(const void *)
{
  int g(const void * b) { return f(a,b); };
  return &g;
}

I get no warning for returning the nested function 'g'.
