Zero-crossings in algorithm sections

[Lennart Ochel]

Events are not triggered for some algorithm sections. The example from r23518 illustrates the issue:

  model ZeroCrossingAlg
    Real a;
    Integer d;
  algorithm
    a := 2*time;
    d := if a > 1.0 then 1 else 2;
    a := 0.5;
  end ZeroCrossingAlg;
