Seems like trying to call Fortran routines from C is not quite
straightforward. Looking at the (draft?) Fortran 2023 spec, page 514 says:
In a reference from C to a Fortran procedure with an interoperable
interface, a C actual argument shall be the address of a C
descriptor for the intended effective argument if the
corresponding dummy argument interoperates with a C formal
parameter that is a pointer to CFI_cdesc_t.
The following section (page 516 onwards) defines these “C descriptors”. Or
alternatively (back to page 514), you might need to declare your Fortran
routine with the “BIND(C)” attribute.
