Comment preserving parsing/unparsing creates hidden duplicate declarations

[Francesco Casella]

Instructions to replicate the problem:

• Start OMEdit and create a new model Test.
• Add the following lines of code:

  model Test
    Integer N = 2;
    Real x[N](each fixed = true);
  equation
    for i in 1:N loop
      der(x[i]) = -x[i];
    end for;
    annotation(Icon(coordinateSystem(initialScale = 1)), Diagram);
  end Test; 
  

• Save the model
• Simulate the model: the compiler correctly complains that dimensions must be parameter or constant expression (in N)
• add the parameter keyword before Integer
• Simulate the model: the following message appears:

  Duplicate elements (due to inherited elements) not identical:
  first element is:  Integer N = 2
  second element is: parameter Integer N = 2
  

Note that if you hit Save, the .mo file does not contain any duplicate lines - they only exist in the library loaded in memory. If I unload and reload the model, it compiles correctly.
