If ALUGrid creates some custom MPI operators and frees them in the destructor, then one needs to make sure that this destructor is called after the one of the MPIHelper (which calls MPI_Finalize). An easy approach would be to set up the MPIHelper in the main method and do the ALUGrid construction in a method that is called afterwards.
