It seems to work (I don't know enough about the code to explain why). I
applied this patch:
--- i/src/xdisp.c
+++ w/src/xdisp.c
@@ -13936,6 +13936,11 @@ redisplay_internal (void)
if (NILP (Vmemory_full))
prepare_menu_bars ();
+ /* prepare_menu_bars may call lisp hooks and hence change the
+ selected_window. */
+ if (WINDOWP (selected_window) && (w = XWINDOW (selected_window)) != sw)
+ sw = w;
+
reconsider_clip_changes (w);
/* In most cases selected window displays current buffer. */
And then following the original recipe does not segfault. There is a
Lisp error, but I think that's already a bug in zoom and/or doom.
