>Could you confirm if the error disappears if you modify rclpy to not free the qos_profile on subscription creation? I confirmed that the error persists even without destroying the qos_profile. >you have exactly the beta3 code without modification except that you are using your own version of rmw_coredx? Correct. I did manage to get a not-so-helpful stack trace from gdb but I don't think it is right yet since it's from publisher.py. I'll keep working on that. --- [Visit Topic](https://discourse.ros.org/t/error-using-python3-nodes-on-arm64-coredx/3057/5) or reply to this email to respond.
