Thanks also to Van-Thuan Pham! Since coreutils-8.24 we have relied on gnulib to indicate whether the system printf routines are safe to use (i.e. crash or not). http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=v8.23-81-gf57bfbb http://git.sv.gnu.org/gitweb/?p=coreutils.git;a=commitdiff;h=v8.23-176-gb817f62 It seems like we'll have to add another check to gnulib to detect this issue in the system libs? I can't reproduce the issue here BTW with ASAN and running in a tight loop for a few minutes. So perhaps it has been fixed in glibc already? I have glibc-2.22-10.fc23.x86_64 Depending on how widespread the issue is will determine if it's worth adding the check to gnulib. What libc are you using? thanks, Pádraig p.s. I tested od with AFL a lot on this system a while back and didn't find any issues.

For completeness, where we discussed the this in relation to gnulib last was: https://sourceware.org/ml/libc-alpha/2015-02/threads.html#00181 and drilling down to there is the reference to original crash bug: https://sourceware.org/bugzilla/show_bug.cgi?id=4586 That was fixed in 2007 so this must be something else. thanks, Pádraig From debbugs-submit-bounces@debbugs.gnu.org Wed Nov 23 22:57:14 2016 Received: (at 25004) by debbugs.gnu.org; 24 Nov 2016 03:57:14 +0000 Received: from localhost ([127.0.0.1]:39842 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1c9l9u-0000nU-G5 for submit@debbugs.gnu.org; Wed, 23 Nov 2016 22:57:14 -0500 Received: from zimbra.cs.ucla.edu ([131.179.128.68]:51326) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1c9l9t-0000nI-6j for 25004@debbugs.gnu.org; Wed, 23 Nov 2016 22:57:13 -0500 Received: from localhost (localhost [127.0.0.1]) by zimbra.cs.ucla.edu (Postfix) with ESMTP id DFA22160084; Wed, 23 Nov 2016 19:57:03 -0800 (PST) Received: from zimbra.cs.ucla.edu ([127.0.0.1]) by localhost (zimbra.cs.ucla.edu [127.0.0.1]) (amavisd-new, port 10032) with ESMTP id xbbglyfyb9Rj; Wed, 23 Nov 2016 19:57:03 -0800 (PST) Received: from localhost (localhost [127.0.0.1]) by zimbra.cs.ucla.edu (Postfix) with ESMTP id 3C0031600A9; Wed, 23 Nov 2016 19:57:03 -0800 (PST) X-Virus-Scanned: amavisd-new at zimbra.cs.ucla.edu Received: from zimbra.cs.ucla.edu ([127.0.0.1]) by localhost (zimbra.cs.ucla.edu [127.0.0.1]) (amavisd-new, port 10026) with ESMTP id r8412nm_32dE; Wed, 23 Nov 2016 19:57:03 -0800 (PST) Received: from [192.168.1.9] (unknown [47.153.178.162]) by zimbra.cs.ucla.edu (Postfix) with ESMTPSA id 1D7F7160084; Wed, 23 Nov 2016 19:57:03 -0800 (PST) Subject: Re: bug#25004: Bug in OD utility To: =?UTF-8?Q?Marcel_B=c3=b6hme?= , =?UTF-8?Q?P=c3=a1draig_Brady?= References: <2741A587-9958-4F81-AF06-87F0523733D1@gmail.com> From: Paul Eggert Organization: UCLA Computer Science Department Message-ID: <030e0425-ed43-36c7-238d-339fa6746ab1@cs.ucla.edu> Date: Wed, 23 Nov 2016 19:57:02 -0800 User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:45.0) Gecko/20100101 Thunderbird/45.4.0 MIME-Version: 1.0 In-Reply-To: Content-Type: text/plain; charset=utf-8; format=flowed Content-Transfer-Encoding: quoted-printable X-Spam-Score: -2.9 (--) X-Debbugs-Envelope-To: 25004 Cc: 25004@debbugs.gnu.org X-BeenThere: debbugs-submit@debbugs.gnu.org X-Mailman-Version: 2.1.18 Precedence: list List-Id: List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Errors-To: debbugs-submit-bounces@debbugs.gnu.org Sender: "Debbugs-submit" X-Spam-Score: -2.9 (--) Marcel B=C3=B6hme wrote: > I can reproduce the crash on Ubuntu 14.04 x86_64 with preinstalled od v= ersion 8.21 and the version in trunk.
