The tutorial cannot pass the test

[axuchao458]

Hello, Professor
I used the content in the tutorial to compile and test, but encountered an error when running the test at the end:

run_test.sh: line 10: 3997 Segmentation fault (core dumped) ./publisher -DCPSConfigFile ../rtps.ini
Publisher exited with status 139
run_test.sh: line 17: 3996 Segmentation fault (core dumped) LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$dir" python3 subscriber.py (wd: ~/snap/pyopendds-master/tests/basic_test)
Subscriber exited with status 139

The version I am using is: opendds 3.30 python 3.10.12
