/* Area:                ffi_call, closure_call

   Purpose:             Check structure returning with different structure size.

                                Depending on the ABI. Check bigger struct which overlaps

                                the gp and fp register count on Darwin/AIX/ppc64.

   Limitations: none.

   PR:                  none.
