pop-to-buffer assumes display-buffer always return a window and
(select-window window norecord) but it can cause error like this (due to
(allow-no-window . t)):

Debugger entered--Lisp error: (wrong-type-argument window-live-p nil)
  select-window(nil nil)
  pop-to-buffer("*compile*" t nil)
  switch-to-buffer-other-window("*compile*")
