index reduction fails for tuple assignment

[Lennart Ochel]

The following model leads wrongly to an over-determined system:

model test
  Real x;

  function f
    input Real t;
    input Real r;
    output Real a;
    output Real b;
  algorithm
    a :=t;
    b :=r;
  end f;
equation
  (,x) = f(time, 5);
end test;

The error message is the following:

Error: Too many equations, over-determined system. The model has 1 equation(s) and 0 variable(s).
Error: Internal error Transformation Module PFPlusExt index Reduction Method Pantelides failed!

This seems to be fixed in the meanwhile.
