Assignment size checks in instance function evaluation

Compiling the model

        function f
            input Integer n;
            output Real[n] y;
            y := zeros(0);
        end f;
        constant Real[:] p1 = f(1);


Exception caught while scalarizing component'p1'org.jmodelica.util.exceptions.InternalCompilerError: Exception caught while scalarizing component'p1'.  Internally the InternalCompileError is caused by a NullPointerException being thrown from 
	at org.jmodelica.modelica.compiler.FVariable.createScalarFVariable(FVariable.java:959)
	at org.jmodelica.modelica.compiler.FVariable.doScalarize(FVariable.java:922)
	at org.jmodelica.modelica.compiler.FVariable.scalarize(FVariable.java:909)

The problem is that the assignment y := zeros(0) is always an empty array, whereas y is sized according to the input n. This should yield an error pointing out the array size mismatch instead.
