Like this

	      (pop-to-buffer
	       debugger-buffer
	       `((display-buffer-reuse-window
		  display-buffer-in-previous-window
                  display-buffer-below-selected)
		 . (,(when (and (window-live-p debugger-previous-window)
				(frame-visible-p
				 (window-frame debugger-previous-window)))
		       `(previous-window . ,debugger-previous-window)))))

I presume.  This will, in the first invocation, make a new window below
the selected one or reuse such a window because there is no previous
window.  Later on, that window gets reused here as expected,
regardless of whether the frame is wide or not.  With emacs -Q, at
least.  Maybe you have additional customizations or changes at work?
