The simplest way to reproduce this is to evaluate:
(define-key isearch-mode-map "\M-m"
(lambda () (interactive) (switch-to-buffer "*Messages*")))
and to type `C-s M-m a' in any buffer except the *Messages* buffer.
The first key activates search mode, the second key switches to the
*Messages* buffer, and the third key continues to search for `a' in
the *Messages* buffer with search mode still enabled.
After exiting the search in the *Messages* buffer and switching back
to the original buffer where the search was activated, the mode line
of the original buffer still displays the "Isearch" string and
isearch-mode is non-nil.
But perhaps this is just an improper key binding for isearch mode
and a valid way to duplicate a global keybinding in isearch mode is
to bind its key to `isearch-other-control-char':
;; existing global key binding:
(define-key global-map "\M-m"
(lambda () (interactive) (switch-to-buffer "*Messages*")))
;; how to allow using the same key binding in isearch-mode:
(define-key isearch-mode-map "\M-m"
'isearch-other-control-char)
This doesn't cause the reported problem.
