Incompatible arguments in _stencil_function

This test reports a compilation issue for functions with pre-defined inputs.

The error disappears when:

1. We provide all inputs to the function call: foo (point, f, true);
2. We do not use the scalar f in a function: commenting test() it works.

double test (double val) {
  return val;
}

passing argument 3 of ’_stencil_foo’ makes pointer from integer without a cast [-Wint-conversion]

double foo (Point point, scalar f, bool vof = true) {
  test (f[]);
  return 1.;
}

scalar f[];

int main (void) {
  init_grid (1 << 5);
  foreach()

incompatible type for argument 2 of ’_stencil_foo’

    foo (point, f);
}
