Memory leak when loading textures in multi-thread

[Tima32]

There is a memory leak:

void _1()
{
        Texture t_up;
        t_up.loadFromFile(String(L"GUI\\Textures\\Up.png"));
}

while (1)
        {
                Thread t(&_1);
                t.launch();
                t.wait();
        }
 

No memory leaks:

void _1()
{
        Texture t_up;
        t_up.loadFromFile(String(L"GUI\\Textures\\Up.png"));
}

while (1)
        {
                _1();
        }

If you repeat the above with RenderWindov there will be a memory leak.
