--- Comment #5 from Harald Anlauf <anlauf at gcc dot gnu.org> ---
Yes, there are some issues.

Note:

      character(kind=c_char,len=*), intent(in) :: c

should not translate to const CFI_cdesc_t* c but to const char *c,
so that one seems correct to me.

Removing the ALLOCATABLE attribute in

      real(c_double), dimension(:), allocatable, intent(inout) :: d

"fixes" this particular one and produces CFI_cdesc_t *d.
