TranslateAndCallTypelessCallback Segmentation fault

@sgf201 after a closer look, it seems the crash happens in libddsc.so. A wild guess would be that either the callback is invalidated but not yet removed from the listener or the callback does something fishy. I would suggest to build the dds layer with debug symbols to get more meaningful information.

I'm closing the issue since it seems highly unlikely to have the root cause in iceoryx itself. Fell free to re-open it if you get more information that points towards iceoryx.

@sgf201 can you create a small example without the ROS/DDS layer and only the iceoryx API?

@elBoberido
Sorry, I can't reproduce this issue in pure iceoryx, and I'm not even familiar with using only iceoryx to implement this feature. This cannot be considered a bug submission. I really want to ask what may have caused this phenomenon. I will pay attention to and troubleshoot it later

There is additional information that this issue occurred when I simultaneously started multiple ROS2 nodes under root, and both roudi and app were started with root privileges. This issue has never occurred when starting with a user
