So actually this are only 22 failing test, but as far as I see this are only 4 different issues. So will create separated tickets for them.

it seems that something in instantiation of function with constants is going wrong, since ""_TinK"", ""_poly_Cp"" and ""_poly_rho"" are constants in package.

For ./simulation/modelica/algorithms_functions/ForIterator2.mos we have some code generation issues with arrays. But I have no idea what kind of issue the cppruntime tests have.

Does anybody something about that issue?
I hope it was not the propose of this module to fix this issue;)
