ColorSelectionDialog csd = new ColorSelectionDialog("Choose a Color"); writefln("csd %s", csd); void* vp = cast(void*) csd.getColorSelection(); ColorSelection cs = cast(ColorSelection) vp; writefln("cs %s", cs); cs.setCurrentColor(cto.baseColor); writeln("A"); Output: csd gtk.ColorSelectionDialog.ColorSelectionDialog cs gtk.Widget.Widget Segmentation fault The segfault is presumably because Widget does not have a setCurrentColor method, but why is the cast being ignored? Is the compiler optimizing the intermediate cast to void away? I don't find the asm from obj2asm helpful. Steve
