Initialization issue with FMUs and C runtime

[Lennart Ochel]

The following example can be used to reproduce an initialization issue with FMUs:

loadString("
model A
  output Real y = x;
  parameter Real x_start = 1.0;
protected
  Real x(start=x_start, fixed=true);
equation
  der(x) = time;
end A;"); getErrorString();

buildModelFMU(A, version="2.0", fmuType="me", platforms={"static"}); getErrorString();

State x is always initialized with 1.0, even if x_start is changed using the FMI interface.

This problem is only related to the C runtime. Everything works just fine with the Cpp runtime.

@lochel, do you think you can take care of this in time for the release of 1.13.0?

Thanks!
