referenced a variable that was not declared as a <variable>

[Lennart Ochel]

This model should probably be simulated without errors:

model foo
  Real a;
  Real b(fixed=true);
initial equation
  pre(a) = b^2;
equation
  der(a) = time;
  when initial() then
    b = pre(a);
  end when;
end foo;

output:

assert            | assert  | Referenced '$PRE._a' that was not declared as <variable>


Process crashed

With +d=initialization I get also:

Assuming fixed start value for the following 1 variables:
         a:VARIABLE() .foo, .Real type: Real

This is wrong. The initial conditions are already fully specified.
