{ %fail }
{ %opt=-Sew }

{ This is a border case:
  the result could be considered to reside only in
  the function result register,
  in which case no stack space would be required... }

  { This is the reason of the -Sew option,
    this test must fail because a warning sould be issued
    about nostackframe without assembler.
    Please do not remove -Sew option. PM 2012-10-17 }
