Bug: Texture crashes at destructor.
« on: July 03, 2017, 02:35:55 am »
#include <SFML/Graphics.hpp>

int WinMain()
{
        sf::RenderTexture t;
        t.create(50, 50);
        return 0;
}

Once in 5-10 runs this program crashes with access violation (both dynamic & static linking).

Backtrace:

Some more notes on strange behavior. There are two classes in the project. Both contain sf::RenderTexture field (different textures) and create it in constructor. One crashes at destructor, other doesn't, but both when destructor is called write warning to output (two flavors appear at random with several consecutive calls):
