My first post here. I'm beginner programmer.
I'm compiling with clang 13.0.1. on Lenovo ThinkPad5 with AMD Ryzen 7 4800U with integrated Radeon Graphics OS: Manjaro linux with kernel 5.10.105 I'm using package allegro 5.2.7.0-2 My compile flags:
-Wall -Wextra -DDEBUG -g -fsanitize=address -fsanitize=undefined -fno-builtin -fno-omit-frame-pointer
I'm getting memory leak error from LeakSanitizer that looks like this:

SUMMARY: AddressSanitizer: 6776 byte(s) leaked in 29 allocation(s).
Maybe I'm missing something important and not deallocating something allocated by allegro functions but I can't find anything in the documentation. My code on github: https://github.com/artqs01/gravity-game.
My code looks like this in the main() function:
int main()
{
srand(time(0));
// Checking if things fail to init
allegro_init();
// Timer init
ALLEGRO_TIMER* timer = al_create_timer(0.013);
al_start_timer(timer);
// Display init
ALLEGRO_DISPLAY* d = al_create_display(1200, 900);
al_clear_to_color(al_map_rgb(0, 0, 0));
// Event queue init
ALLEGRO_EVENT_QUEUE* eq = al_create_event_queue();
ALLEGRO_EVENT e;
allegro_register_events(eq, d, timer);
//Font init
ALLEGRO_FONT* font = al_load_ttf_font("../fonts/consola.ttf", 20, 0);
if (!font)
{
printf("font not loaded\n");
return 1;
}
//Mouse control init
ALLEGRO_MOUSE_STATE cur_ms;
al_get_mouse_state(&cur_ms);
ALLEGRO_MOUSE_STATE prev_ms;
//Camera transformation init
ALLEGRO_TRANSFORM transf;
ctrl_cam_ctrler c_ctrl = ctrl_create_cam_ctrler();
// Main loop control variable init
ctrl_loop_ctrler l_ctrl = ctrl_create_loop_ctrler();
// Time measure variable init
ctrl_time_ctrler t_ctrl = ctrl_create_time_ctrler();
obj arro[2];
arro[0] = obj_create(20.f, 1000.f, -1000.f, (vect2){300.f, 300.f}, (vect2){10.f, 0.f});
arro[1] = obj_create(10.f, 100.f, 1000.f, (vect2){600.f, 600.f}, (vect2){0.f, -10.f});
const int size = sizeof(arro) / sizeof(obj);
// Main loop
while (l_ctrl.alive)
{
ctrl_measure_dt(&t_ctrl);
al_wait_for_event(eq, &e);
ctrl_manage_event(eq, &e, &l_ctrl);
if (!l_ctrl.pause)
{
obj_update(arro, size, t_ctrl.dt);
}
if (l_ctrl.step)
{
l_ctrl.pause = 1;
l_ctrl.step = 0;
}
ctrl_set_zoom(&cur_ms, &prev_ms, &c_ctrl);
ctrl_transform(&transf, &c_ctrl);
ctrl_mouse_state_update(&cur_ms, &prev_ms, &c_ctrl);
draw(arro, size, font);
al_flip_display();
}
// Cleaning up
al_destroy_display(d);
al_destroy_event_queue(eq);
al_destroy_timer(timer);
al_destroy_font(font);
return 0;
}
Maybe You know if it's something related to my poorly written code or the graphics driver. I'm getting similar leaks on my desktop with Intel core i5 4460 and Geforce GTX 970 (same OS).
Thanks!
