/* Area:        ffi_call, closure_call

   Purpose:     Check structure passing with different structure size.

                Depending on the ABI. Darwin/AIX do double-word

                alignment of the struct if the first element is a double.

                Check that it does not here.

   Limitations: none.

   PR:          none.
