After running the phoxi_camera_node, I encountered an 'invalid pointer' error. #1

The operating environment is ROS Galactic. The 'colcon build' process has also passed successfully. When executing the phoxi_camera_node, an error 'free(): invalid pointer' occurs, and the program crashes. Please help me resolve this issue. Thank you very much！

Same for me :(

So I continued to investigate a bit here. What I got so far is (and I do not know why) that if you run the node with a debugger it does not throw the "invalid pointer" error. This is also a bit unfortunate for the whole debugging process but could potentially be used for a hacky workaround. 

ros2 run --prefix 'valgrind' phoxi_camera phoxi_camera_node

The thing that is a problem after this is that I do not get any messages published on the ROS topics. Any ideas what the problem here could be?

(... another thing. At one point this week I did NOT get the pointer error anymore. And then all of a sudden it reappeared. I am somewhat clueless what the main cause here is.)
