Date: Fri, 25 Jan 2013 03:34:53 -0500 [thread overview]
Message-ID: <g2ip6lu0cy.fsf@fencepost.gnu.org> (raw)

>> Why is this issue (apparently) only seen in Python mode
Answering my own question, it happens in any mode that sets
imenu-prev-index-position-function and
imenu-extract-index-name-function, but there are very few of those.
Eg prolog mode. With buffer contents:
------
fac(0,1).
fac(N,F) :- N > 0, M is N - 1,
fac(M,Fm), F is N * Fm.
------
and point at point-min, switching to prolog-mode causes the same issue.
How about taking the more cautious approach with:
(when (and (= pos (point))
(not (bobp)))
(error "Infinite loop... ))
(IIUC, this was actually the suggestion in
http://lists.gnu.org/archive/html/emacs-devel/2013-01/msg00510.html ?)
