SFML 2.0 Memory Leak?
« on: August 02, 2012, 04:33:20 pm »
Hello.

I just compiled SFML 2.0 myself with MinGW 4.7. I made a minimal RenderWindow with an event loop and found out that the memory usage of the program keeps rising. So I removed the event loop and found out that the problem is either in the clear() or display() function.

Using this code:

#include <SFML/Graphics.hpp>

int main()
{
    sf::RenderWindow App(sf::VideoMode(640, 480), "Leak");

    while(App.isOpen())
    {
        App.clear();

        App.display();
    }

    return 0;
}
 

compiled with MinGW 4.7 on Windows 7 64bit statically linked the memory usage starts at about 27-28 MB and then starts rising.

It's most likely a leak in your graphics driver. Is it up to date?

Yep. My graphics drivers are up to date.

Does "just" mean right now, like commit db1f1b8fa1006ea440b9cbe4a2d61b632109ebb2?

...the memory usage starts at about 27-28 MB and then starts rising.
Define rising a bit more. A few bytes per second or 100MB a minute?

Additionally there are tools to find the source of memory leaks, so it's adviced to use one and tell us where/what is leaking. ;)

I compiled the source from 31 june.

In the beginning it rises somewhere between 20 and 100 kB/s with occasional 2-3 MB rises. Then after a minute or so it gets static for a couple of second at around 48 MB then rises with about 3-6MB and keeps going on like that - pause - rise - pause - rise.

Could you recommend me one of those tools? :P
