I've fixed it using C-delete and C-M-delete (which are clearer anyway)
in the examples.

emacs -Q
 
Try evaluating either of these examples from (elisp) Defining Minor
Modes:
 
(define-minor-mode hungry-mode
       "Toggle Hungry mode.
     With no argument, this command toggles the mode.
     Non-null prefix argument turns on the mode.
     Null prefix argument turns off the mode.
 
     When Hungry mode is enabled, the control delete key
     gobbles all preceding whitespace except the last.
     See the command \\[hungry-electric-delete]."
      ;; The initial value.
      nil
      ;; The indicator for the mode line.
      " Hungry"
      ;; The minor mode bindings.
      '(("\C-\^?" . hungry-electric-delete))
      :group 'hunger)
 
(define-minor-mode hungry-mode
       "Toggle Hungry mode.
     With no argument, this command toggles the mode.
     Non-null prefix argument turns on the mode.
     Null prefix argument turns off the mode.
 
     When Hungry mode is enabled, the control delete key
     gobbles all preceding whitespace except the last.
     See the command \\[hungry-electric-delete]."
      ;; The initial value.
      :init-value nil
      ;; The indicator for the mode line.
      :lighter " Hungry"
      ;; The minor mode bindings.
      :keymap
      '(("\C-\^?" . hungry-electric-delete)
        ("\C-\M-\^?"
         . (lambda ()
             (interactive)
             (hungry-electric-delete t))))
      :group 'hunger)
 
Both raise this error:
 
Debugger entered--Lisp error: (error "Invalid modifier in string")
