When a scenario is over, you get a message about the result (e.g. "Axis Minor Victory"). After that you can see the whole map again. Now it is still possible to select "Request Reinforcements". If you click on it, a segmentation fault is triggered:
Program received signal SIGSEGV, Segmentation fault.
