The relevant commit (here linked from github):
https://github.com/emacs-mirror/emacs/commit/8635147ccba1fc8e1010010da8c3f8e467562f76#diff-10f71b5f4495401d9de9677a0836462b
With this latest change, if `imenu-auto-rescan` is set to `t` then
calling `imenu--index-alist` will return `nil`. The fix is to change
`(unless imenu-auto-rescan (cons ...))` to
`(if imenu-auto-rescan imenu--index-alist (cons ...))` in `imenu.el`.
Reproduction steps:
- Visit a file that supports `imenu` (e.g. an elisp buffer with some
functions defined)
- C-M-; (setq imenu-auto-rescan nil)
- M-x imenu
- There should be items in the list
- C-M-; (setq imenu-auto-rescan t)
- M-x imenu
- The list should be empty

I've attached a patch to fix the bug. The fix is that, if
`imenu-auto-rescan` is enabled, the current `imenu--index-alist` is
returned, otherwise it's returned with the `*Rescan*` option.
