Memory leak in basic freeglut program - c++

Question

I'm trying to make a simple freeglut application. I have the following code:
#include "GL/freeglut.h"
#include "glm/glm.hpp"
// global and state variables
namespace globals {
const int screen_width = 720;
const int screen_height = 720;
const int window_position_x = 100;
const int window_position_y = 100;
const glm::vec4 clear_color (0.2f, 0.2f, 0.2f, 1.0f);
}
void display ();
int main (int argc, char** argv) {glutInit(&argc, argv);
// initialize GLUT window size, position, display mode
glutInitWindowSize(globals::screen_width, globals::screen_height);
glutInitWindowPosition(globals::window_position_x, globals::window_position_y);
glutInitDisplayMode(GLUT_RGB | GLUT_DOUBLE);
// continue execution after window is closed by user
glutSetOption(GLUT_ACTION_ON_WINDOW_CLOSE, GLUT_ACTION_CONTINUE_EXECUTION);
// create a window
glutCreateWindow("Simple GLUT Template");
// setup a display callback that GLUT calls for every render
glutDisplayFunc(display);
// start main loop
glutMainLoop();
return 0;
}
void display () {
using namespace globals;
glClearColor(clear_color.r, clear_color.g, clear_color.b, clear_color.a);
glClear(GL_COLOR_BUFFER_BIT);
glutSwapBuffers();
}
I initialise the program to work with GLUT and create a simple window. For compilation, I use this:
g++ -Wall -Wextra -pedantic -g -DDEBUG_MODE -D_GLIBCXX_DEBUG -fsanitize=address,undefined -lGL -lGLU -lglut simple-glut-template.cpp -o simple-glut-template
When I execute the program and close the window, the address sanitizer seems to pick up on a lot of memory leakage that I cannot seem to fix (output shared below). Any help on understanding what's happening is appreciated. Thanks!
