Could it be that your palette is nothing more than a window
with nothing inside? Fl::pushed() would return the window,
w->window() would return NULL,
and while(win->window()) would crash on dereferencing a NULL pointer.
This would be corrected by:
Fl_Widget *w = Fl::pushed();
Fl_Window *win = w->window();
if(win == NULL) { win = (Fl_Window*)w; }
else { while(win->window()) win = win->window(); }
