Crash while calling SDL_DestroyTexture() SDL 1.3 windows

SDL Development

hi i have a problem with sdl 1.3:

when calling:

SDL_DestroyTexture()

i crash with an unhandled exception. has anybody an idea what could goes wrong??

code snippet:

Code:

void connect()
{

        SDL_Init(SDL_INIT_VIDEO);
        SDL_SelectVideoDisplay(params_.displayId_);

        SDL_DisplayMode requestedMode;
        requestedMode.w = params_.widthInPixels_;
        requestedMode.h = params_.heightInPixels_;
        requestedMode.refresh_rate = static_cast<int>(params_.frequencyInHz_ + 0.5);
        requestedMode.format = static_cast<UInt>(SDL_PIXELFORMAT_RGBA8888);
        if (SDL_GetClosestDisplayMode(&requestedMode, &mode_) == NULL)
            throw Error("Image size is not supported by selected display.");

        Uint32 flags = SDL_WINDOW_SHOWN | SDL_WINDOW_FULLSCREEN | SDL_WINDOW_OPENGL;
        window_ = SDL_CreateWindow("Output", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, params_.widthInPixels_, params_.heightInPixels_, flags);
        if (window_ == NULL)
            throw Error("Could not create window for output.");

        SDL_SetWindowDisplayMode(window_, &mode_);
        SDL_CreateRenderer(window_, -1, SDL_RENDERER_PRESENTDISCARD | SDL_RENDERER_PRESENTVSYNC  | SDL_RENDERER_ACCELERATED ); 
        SDL_SelectRenderer(window_);

        texture_ = SDL_CreateTexture(mode_.format, SDL_TEXTUREACCESS_STREAMING, params_.widthInPixels_, params_.heightInPixels_);
        if (texture_ == NULL)
            throw Error("Could not create texture for output.");

        imagebuffer_ = new Uint32[mode_.w * mode_.h];
        if (imagebuffer_ == NULL)
            throw Error("Out of memory.");
    }

void disconnect()
{
if (isSDLOk_)
{
if (imagebuffer_ != NULL)
{
delete imagebuffer_;
}

            if (texture_ != NULL)
            {
	    SDL_DestroyTexture(texture_);
                texture_ = NULL;
            }

            if (window_ != NULL)
            {
	    SDL_DestroyWindow(window_);
                window_ = NULL;
            }

            SDL_SelectVideoDisplay(0);
            SDL_Quit();
            isSDLOk_ = false;
        }
    }

as far as i don’t call the lines it doesn’t crash by my intention of using sdl neither :wink:

Code:

SDL_CreateRenderer(window_, -1, SDL_RENDERER_PRESENTDISCARD | SDL_RENDERER_PRESENTVSYNC | SDL_RENDERER_ACCELERATED );
SDL_SelectRenderer(window_);

any ideas what could go wrong in here?

thx,
