stack smashing detected combining ROS2 node an gzclient [closed]

I'm trying to create a simple node that listens to Gazebo transport messages and republishes them on ROS2.

When I try to run the client/node I get the following error (Backtrace at the end of the message)

*** stack smashing detected ***: <unknown> terminated

The reason I suspect Gazebo is that the stack smash only happens when I actually start the gz server. Also, while the backtrace points at the FastRTPS XML loading code, if I spin the ROS node and then start the gz server, it will crash after I start the server.

I've created the following stub code to test. If you remove the allocation of std::shared_ptr<gazeborealsensebridge> bridge it will not crash. This code will only crash if the gzserver is running.

#include <iostream>
#include <memory>

#include <rclcpp/rclcpp.hpp>
#include <sensor_msgs/msg/point_cloud2.hpp>

#include <gazebo/transport/transport.hh>
#include <gazebo/msgs/msgs.hh>

#include <gazebo/gazebo_client.hh>

class GazeboRealSenseBridge : public rclcpp::Node
    GazeboRealSenseBridge() : rclcpp::Node("gazebo_realsense_bridge")
        publisher = this->create_publisher<sensor_msgs::msg::PointCloud2>("realsense_pointcloud");


    rclcpp::Publisher<sensor_msgs::msg::PointCloud2>::SharedPtr publisher;


int main(int argc, char **argv)
    rclcpp::init(argc, argv);
    gazebo::client::setup(0, nullptr);

    std::shared_ptr<GazeboRealSenseBridge> bridge = std::make_shared<GazeboRealSenseBridge>();

    std::map<std::string, std::list<std::string> > messageTypesAndTopics = gazebo::transport::getAdvertisedTopics();
    for(auto it = messageTypesAndTopics.begin(); it != messageTypesAndTopics.end(); it++)
        for(auto topicIt = it->second.begin(); topicIt != it->second.end(); topicIt++)
            std::cout << *topicIt << " (" << it->first << ")" << std::endl;

//    rclcpp::spin(bridge);
    return 0;

Appendix - Backtrace

I think this backtrace is suspect, as it will show the same backtrace if you spin the ros node and start the server later. This code should not continuously run.

My bad. Recompiling ROS2 from source fixed the issue.
