Sample of this bug, it'll set RENDER_BUG at 1 after SDL_SetWindowSize

Hello,
By switching my app from SDL 1.2 to 2.0, I experimented a lot of weird bugs where create textures fail inexplicably.
By investigating, I succed at reproduce the crash in a really short code (linked).

I reproduce the bug with a 100% accuracy on my 64bits laptop/desktop, running both AMD and Intel CPU, both with ATI graphical cards and with updated pilots.
On a 32 bit netbook with a Intel graphical chip/Atom CPU, the bug never happen.
I work with MinGW, fully updated, it compiled by build of the SDL.

By looking at SDL_GetError(), I get "CreateTexture(): INVALIDCALL".
I went as deep as I could and it fails after a DirectX call. (I've DirectX updated SDK installed on my laptop).

Thanks in advance to look into this bug.

Hello, as I don't see any answer, here is a new (compilable) sample

int main()
{
    if(SDL_Init(SDL_INIT_VIDEO)) //launch the SDL and check for failure
        return 0;

    SDL_Window *windows = SDL_CreateWindow("Trigger the bug", 50, 25, 50, 75, SDL_WINDOW_OPENGL);
    SDL_Renderer *renderervar = SDL_CreateRenderer(windows, -1, SDL_RENDERER_ACCELERATED);
    SDL_SetWindowSize(windows, 100, 150);
    SDL_RenderClear(renderervar); //Failed, SDL_GetError send "Reset(): INVALIDCALL", and then, any attempt to create texture will fail: the only fix is to destroy the render variable and create it again.
}

Can you try in the latest snapshot?

Somebody reported a similar bug, which was fixed.

Thanks!
