I've got a "Stack overflow in regexp matcher" error on startup as I've
made an Org file my initial buffer.  It took me days to reproduce this
error (by putting `(setq debug-on-error t)` into my init file and
forgetting about the bug until the error resurfaced), but I've finally
managed to catch its backtrace:

Debugger entered--Lisp error: (error "Stack overflow in regexp matcher")
  looking-at("[     ]*\\(\\S-+\\)\\(.*[     ]+::\\)?\\([     ]+\\|$\\)")
  org-list-item-body-column(1297)
  org-indent-add-properties(#<marker at 1 in *notes*> 93050 (0 2 0))
  org-indent-initialize-buffer(#<buffer *notes*> (0 2 0))
  org-indent-initialize-agent()
  apply(org-indent-initialize-agent nil)
  timer-event-handler([t 0 0 200000 t org-indent-initialize-agent nil idle 0])

The easiest solution to this would be probably a rewrite of the faulty
regexp to not backtrack as much.  93050 is `(point-max)` in the file,
the marker does not point to any buffer and does therefore not have any
inspectable position.
