This testcase is a reduced version of a problem that happens in
the "matrix-client.el" package (available on alphapapa's GitHub):
(require 'cl-lib)
(require 'pcase)
(cl-macrolet
((message-self () `(message self)))
(pcase-let ((`(,self ,self2) '("1" "2")))
(message-self)))
Behavior before commit a218c9861573b5ec4979ff2662f5c0343397e3ff
("lisp/emacs-lisp/pcase.el: Don't bind unused vars in branches"):
outputs 1 to the minibuffer.
Behavior after the commit: Symbol’s value as variable is void: self
Best,
Mauricio
