In SDL_CreateTextureFromSurface:

SDL_PixelFormat *dst_fmt;
/* Set up a destination surface for the texture update */
         dst_fmt = SDL_AllocFormat(format);
            temp = SDL_ConvertSurface(surface, dst_fmt, 0);

Here is need of NULL check for dst_fmt because there are chances of NULL return from SDL_AllocFormat(format);

so it should be like that:

        SDL_PixelFormat *dst_fmt;
        SDL_Surface *temp = NULL;

        /* Set up a destination surface for the texture update */
        dst_fmt = SDL_AllocFormat(format);
        if (!dst_fmt) {
            SDL_DestroyTexture(texture);
            return NULL;
        }

        temp = SDL_ConvertSurface(surface, dst_fmt, 0);
        SDL_FreeFormat(dst_fmt);


Thanks!!!
