Edit: found the issue, my bad.
Thank you all for your valuable feedback! I have learnt a lot already while testing the below steps. However, my failure was rather trivial - the PC I have borrowed from our IT did only have 8GB of RAM, which is not enough according to the example tutorial of the pendulum_demo it requires at least 8GB of free RAM.
I failed to check the PC specs and the requirement in the example manual. However, it is interesting to note that not only the pendulum_demo, but also example_loop from ros2/realtime_support/rttest required more RAM than was available in the tested PC. By using htop in a seperate console I could follow how the memory is filled after either programm start and the programm being killed exactly once the memory is full.

Before you run make sure you have at least 8Gb of RAM free. With the memory locking, swap will not work anymore.
