Code generation error for tuple calls with array slices

[Martin Sjölund]

Code generation fails with UNKNOWN_SUBSCRIPT for the following code:

function f
  input Real r;
  output Real y = r;
  output Real o[3] = {r,r,r};
end f;

function g
  input Real r;
  input Integer i;
  output Real o[4];
algorithm
  o[1] := f(r);
  (,o[i:i+2]) := f(r);
  (o[1],o[i:i+2]) := f(r);
end g;

model M
  Real r[4] = g(time,1);
end M;
