I got lock-order-inversion with ThreadSanitizer

[SdKay]

Ubuntu18.04 melodic my code, I want to check if there is a node with same name before I init

#include <ros/ros.h>
#include <stdio.h>

#define LOG() printf("[%d]\n", __LINE__)

int main(int argc, char ** argv)
{
    std::string node_name = "main";
    LOG();

    //init for check
    ros::init(argc, argv, "pre_check", ros::init_options::AnonymousName);

    std::vector<std::string> nodes;
    ros::master::getNodes(nodes);
    for(auto & node : nodes) {
        if("/" + node_name == node) { //check if another node with name "node_name" exists
            ros::shutdown();
            LOG();
            return -1;
        }
    }
    LOG();
    ros::shutdown();
    LOG();
    ros::waitForShutdown();
    LOG();

    //start work node
    ros::init(argc, argv, node_name);

    //do some work

    ros::spin();
}

build and run with LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libtsan.so.0, i got this
