New to arch linux - problem with opengl/c++ project -memory leak

Hello community.

Two weeks ago I decied to dive into arch linux.
Goals was to move from windows completely, but got stuck into running one of my projects in c++.

I have this project in c++, opengl project and there I have one unit test that throws error message about memory leak from files libasan.h and libnvidia-glcore.
I searched the internet and got impression that I should get used to this kinda problem with nvidia.
Still I did try couple of things like changing the version of nvidia driver, more specific i am using nvidia-dkms driver.
Changing version did not help. Still got same issue that memory is leaking.

Code is actually very simple. I am just creating window/context, not drawing anything, just simple open and close window

    static void SetUpTestSuite() {
        // Initialize once
        glfwWindowHint(GLFW_CONTEXT_VERSION_MAJOR, 4);
        glfwWindowHint(GLFW_CONTEXT_VERSION_MINOR, 6);
        glfwWindowHint(GLFW_OPENGL_PROFILE, GLFW_OPENGL_CORE_PROFILE);
        glfwWindowHint(GLFW_VISIBLE, GLFW_FALSE);
        glfwInitHint(GLFW_PLATFORM, GLFW_PLATFORM_X11);

        if (!glfwInit()) {
            std::cerr << "Failed to initialize GLFW!" << std::endl;
        }
    }

    static void TearDownTestSuite() {
        glfwTerminate();
    }

    void SetUp() override {

        window = glfwCreateWindow(1, 1, "", nullptr, nullptr);
        if (!window) {
            std::cerr << "Failed to create GLFW window!" << std::endl;
        }
        glfwMakeContextCurrent(window);
        int version = gladLoadGL(glfwGetProcAddress);
        std::cout << glGetString(GL_VENDOR) << std::endl;
        std::cout << "OpenGL Version: " << glGetString(GL_VERSION) << "  GLAD version " << version << std::endl;

        GLenum error = glGetError();
        EXPECT_EQ(GL_NO_ERROR, error);
    }
--------------------------------------------------------------------------------------------------------------------------------------------------------------------
Error that I get is this.

Re: New to arch linux - problem with opengl/c++ project -memory leak

ignore the leaks and run with `ASAN_OPTIONS=detect_leaks=0` or more selectively. If not, create/define smtg like this leak `libnvidia-glcore.so` `leak:libdbus-1.so` and run with  `ASAN_OPTIONS=detect_leaks=1:suppressions=asan.supp`, option3, Disable LSan only (keep ASan)...
