Note, even just
  foo ({});
outside of range-for has its temporaries without pushdecl.
  const struct D D.2692;

...
              try
                {
                  D::D (&D.2692);
                  try
                    {
                      D.2693 = foo (&D.2692); [return slot optimization]
                      A::~A (&D.2693);
                    }
                  finally
                    {
                      D::~D (&D.2692);
                    }
                }
              finally
                {
                  D.2692 = {CLOBBER(eos)};
                }

  Guess for coro that would be about co_await qux ({}); or similar for qux with
const D & operand.
But in the range-for case, the lifetime of those temporaries doesn't end at the
end of the statement but is until the end of the range for body.
