Subject: [PATCH] Fixed bug 1403 - Creating a window with resizable flags may
 crash

jordirovira 2012-01-28 12:07:39 PST

in SDL_x11window around 520:

    /* Setup the normal size hints */
    if (!(window->flags & SDL_WINDOW_RESIZABLE)) {
        sizehints.min_width = sizehints.max_width = window->w;
        sizehints.min_height = sizehints.max_height = window->h;
        sizehints.flags = PMaxSize | PMinSize;
    }
    sizehints.x = window->x;
    sizehints.y = window->y;
    sizehints.flags |= USPosition;

the sizehints.flags member is not initizalised if it doesn't enter the
conditional. It is as easy as setting it to zero before the conditional.
