I have a core file. What is this, an epidemic? FWIW, I cannot find any change during the last 2 weeks that could somehow be related. > hlinfo->mouse_face_window is non-nil but contains garbage. We could add a WINDOWP test where we currently use !NILP, before the call to show_mouse_face in clear_mouse_face, but that would be a band-aid. Where could this garbled "window" come from? some GC or memory-allocation snafu?
