Archived-At:
Insert the following into /tmp/rec.el:
;; -*- lexical-binding: t; -*-
(require 'cl-lib)
(defun recurse (i g)
(if (=3D i 0)
(funcall g (cl-gensym))
(recurse (1- i) g)))
(recurse 100 (lambda (sym)
(message "outer: %s" sym)
(mapbacktrace
(lambda (_ _ args _)
(recurse 100 (lambda (sym)
(message "inner: %s %s" sym args)))))))
Then run
emacs -Q -batch -l /tmp/rec.el
=20=20
The printed messages will either be way too short, or Emacs will
segfault. Re-running the command a couple of times consistently
generated a segfault for me.
My guess is that pdlvec got reallocated, but Fmapbacktrace uses pointers
instead of indices to access its element, so they pointers became
invalidated and point to garbage.
