Re: Understanding the cause of a bug causing *all* bindings to be wiped out

[Kaushal Modi]

I am using the emacs master build version (25.1.50.x).

Here is how I set my minor mode map:

=====

(defvar modi-mode-special-map (make-sparse-keymap)

  "Special keymap for `modi-mode' whose bindings begin with

`modi-special-keymap-prefix'.")

(fset 'modi-mode-special-map modi-mode-special-map)

(defvar modi-mode-map (let ((map (make-sparse-keymap)))

                        (define-key map modi-special-keymap-prefix 'modi-mode-special-map)

                        map)

  "Keymap for `modi-mode'.")

;; The keymaps in `emulation-mode-map-alists' take precedence over

;; `minor-mode-map-alist'

(add-to-list 'emulation-mode-map-alists `((modi-mode . ,modi-mode-map)))

=====

Also there was a typo in my previous email:

I meant:

=====

The strange thing is that 

(string-match "." nil) ; *not* (string-match-p ..)

generates proper backtrace as expected ..

The overriding-local-map if non-nil disables all other maps.
And in Emacs<24.4, the same holds for overriding-terminal-local-map.

Could it be you're using a package written for Emacs>=24.4 which sets
a sparse keymap in overriding-terminal-local-map to just override a few
key bindings, but you use it with Emacs<24.4 where that ends up
disabling all other bindings?
