Subject: bug#16520: 24.3.50; cl-defstruct with :predicate option
Date: Wed, 22 Jan 2014 11:06:34 +0100 [thread overview]
Message-ID: <m2zjmoqqj9.fsf@gmail.com> (raw)
Compiling this code:
(require 'cl-lib)
(cl-defstruct (foo (:predicate foop)))
(defun bar (x) (cl-check-type x foo))
with with: emacs -Q -batch -f batch-byte-compile foo.el
produces this warning:
foo.el:8:1:Warning: the function `foo-p' is not known to be defined.
and since foo-p is not defined will also lead errors at run-time when
bar is called.
Adding eval-and-compile to the structure definition avoids the problem
but it's a bug that the compiler emits a call to foo-p at all.
