(defmacro buggy () (assert nil nil "assertion failed -- it always should fail") "This should never show up!") This only seems to happen when i compile a file containing the macro, not when i compile the macro individually. Here is a full example (the defmacro of `buggy' is in the file "bug.test.el") (declaim (optimize (safety 3))) (byte-compile-file "bug.test.el" 'load) ; t (buggy) ; error: "assertion failed -- it always should fail" (declaim (optimize (safety 0))) (byte-compile-file "bug.test.el" 'load) ; t (buggy) ; This should never show up! I'm not sure whether this officially qualifies as a bug, but it's certainly not the behavior I was expecting. (It also doesn't seem to be present in Emacs 23.1.1) Thanks, Rafael ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- Rafael Sorkin Perimeter Institute for Theoretical Physics 31 Caroline Street North Waterloo, ON N2L 2Y5 Canada ~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~-~- From debbugs-submit-bounces@debbugs.gnu.org Mon Apr 27 00:04:13 2015 Received: (at control) by debbugs.gnu.org; 27 Apr 2015 04:04:13 +0000 Received: from localhost ([127.0.0.1]:40744 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.80) (envelope-from ) id 1YmaHF-0004St-8X for submit@debbugs.gnu.org; Mon, 27 Apr 2015 00:04:13 -0400 Received: from ironport2-out.teksavvy.com ([206.248.154.181]:6752) by debbugs.gnu.org with esmtp (Exim 4.80) (envelope-from ) id 1YmaHC-0004Sa-RC; Mon, 27 Apr 2015 00:04:11 -0400 X-IronPort-Anti-Spam-Filtered: true X-IronPort-Anti-Spam-Result: AgUFAGvvdVRMCqjW/2dsb2JhbAA3gVOhb4EIgXUBAQQBViMFCws0EhQYDSSIE6IRjGQJAQIBAoM+A4NwBKNjhFg X-IPAS-Result: AgUFAGvvdVRMCqjW/2dsb2JhbAA3gVOhb4EIgXUBAQQBViMFCws0EhQYDSSIE6IRjGQJAQIBAoM+A4NwBKNjhFg X-IronPort-AV: E=Sophos;i="5.11,557,1422939600"; d="scan'208";a="117502178" Received: from 76-10-168-214.dsl.teksavvy.com (HELO ceviche.home) ([76.10.168.214]) by ironport2-out.teksavvy.com with ESMTP/TLS/DHE-RSA-AES256-SHA; 27 Apr 2015 00:04:06 -0400 Received: by ceviche.home (Postfix, from userid 20848) id 333BB6610A; Mon, 27 Apr 2015 00:04:05 -0400 (EDT) From: Stefan Monnier To: Rafael D Sorkin Subject: Re: bug#20427: bug in optimizing compiler?

That's expected. Just like C's `assert', CL's `assert' can be compiled out depending on compilation options (in this case, depending on the `safety' setting).
