Description
The issue here is of course that constants in Modelica aren't constants at
all. They can be modified when extending, etc (how fun!).
So consider the model below. Right now, OpenModelica will look at
reference_X and say: This function takes input Integer[3]. And will then
happily cache the result. Then we try to call this function below with
an Integer[4], and we get an error. We could also extend from this model
twice and setting reference_X to different dimensions in both :)
model evil constant Integer[:] reference_X = {1,2,3}; function set input Integer X[:] = reference_X; output Integer x1; algorithm x1 := X[1]; end set; Integer res1; equation res1 = set({4,5,6,7}); end evil;
