Ok, after recompiling with only "X11" flag and running the programm in debug Mode :

The programm crash at this line : (ImageX11.cpp, CtrlCore)
void ImageDraw::Init()
{
	GuiLock __;
	dw = XCreatePixmap(Xdisplay, Xroot, max(size.cx, 1), max(size.cy, 1), Xdepth);  //This line generate the crash
	gc = XCreateGC(Xdisplay, dw, 0, 0);
	xftdraw = XftDrawCreate(Xdisplay, (Drawable) dw, DefaultVisual(Xdisplay, Xscreenno), Xcolormap);

	alpha.dw = XCreatePixmap(Xdisplay, Xroot, max(size.cx, 1), max(size.cy, 1), Xdepth);
	alpha.gc = XCreateGC(Xdisplay, alpha.dw, 0, 0);
	alpha.xftdraw = XftDrawCreate(Xdisplay, (Drawable) alpha.dw, DefaultVisual(Xdisplay, Xscreenno), Xcolormap);

	Vector<Rect> clip;
	clip.Add(RectC(0, 0, size.cx, size.cy));
	SystemDraw::Init(clip, Point(0, 0));
	alpha.Init(clip, Point(0, 0));

	has_alpha = false;
}


The PANIC message on console is :
****************** PANIC: Invalid memory access!
