This looks like a libffi bug to me, so I'm CCing
libffi-discuss@sourceware.org

The 6th argument of ffi_call_AIX and ffi_call_DARWIN is given as
    void (*fn2)(void)
in the prototype, but they are being passed ffi_prep_args, which has
type
    void ffi_prep_args(extended_cif *ecif, unsigned *const stack)

The latest release (3.0.8) looks like it has the same problem.
