sorting of protected variable in a function

[Willi Braun]

Following model fail due to using not initialized memory:

ModelicaTest.Fluid.Dissipation.Verifications.HeatTransfer.StraightPipe.kc_overall_KC

It seems that we sort the protected variables in a function wrong or actually we don't sort them at all, if there is an if-expression involved.

loadString("
function f
  input Real x;
  output Real y;
protected
  Real a = sin(x);
  Real b = if  x > 0 then cos(a+c) else 0;
  Real c = cos(a+b);
algorithm
  y := c;
end f;

model A
 Real x(start=1);
equation
  der(x) = f(x);
end A;
"); getErrorString();
simulate(A); getErrorString();

Where is this sorting performed?
