Some functions in undo-tree refer to or manipulate Emacs undo
internals:

  undo-list-pop-changeset
  undo-list-transfer-to-tree
  undo-list-rebuild-from-tree
  undo-tree-pull-undo-in-region-branch
  undo-tree-pull-redo-in-region-branch
  undo-tree-adjust-elements-to-elt
  undo-tree-apply-deltas
  undo-tree-undo-1
  undo-tree-redo-1

Do they perhaps need some adjustments to Emacs 25's undo?

Another potential issue is the new undo timer we have in Emacs 25 (see
undo-auto--boundary-ensure-timer in simple.el).  One way of checking
whether this is related to the crashes is to modify that function to
use a much larger value for the 1st argument of run-at-time, say
10000, so that the undo timer never fires during the startup.  Reuben,
could you try that?
