[deal.II] Segfault when calling gather_evaluate() or read_dof_values_plain()

I tried to implement a RK4-solver similar to the upcoming example 67 using the matrix-free technique, and compare it to other solvers I wrote earlier. For this purpose I chose the classical heat-equation for testing. When running the attached example, though, I get a segfault when calling either
