Inverse algorithms with discrete variables are failing

[Willi Braun]

Following example fails with segmentation fault:

model InverseAlgorithm4
  Real x;
  Real w;
  Integer y,z;
equation 
  der(x) = y;
  when sample(0,0.1) then
    w = x+sin(time);
    y = integer(sin(x)*w)*10;
    z = integer(y);
  end when;
initial algorithm 
  y := integer(w);
  z := integer(y);
end InverseAlgorithm4;

This is issue was observed in bigger models.
