When in your original test case '(pop-to-buffer "*Occur*")'
is replaced with '(kill-current-buffer)':

  (define-key isearch-mode-map (kbd "M-s o")
    #'(lambda ()
        (interactive)
        (call-interactively 'isearch-occur)
        (kill-current-buffer)))

then it fails with:

  Error in post-command-hook (isearch-post-command-hook): (error "Selecting 
deleted buffer")

All other uses of 'isearch--current-buffer' have a check
for a live buffer, e.g.

  (unless (eq (current-buffer) isearch--current-buffer)
    (when (buffer-live-p isearch--current-buffer)
      (with-current-buffer isearch--current-buffer
