I also tried building Guile 3.0.0 on Cygwin 3.1.x. The failure comes from trying to parse compiled .go files. The last time that I had this sort of problem, it was because the O_BINARY flag was dropped or missing when writing .go files, leading to CR+LF characters in the compiled files. And I diagnosed it by byte-comparing Linux-compiled .go files with Cygwin-compiled .go files, and by looking for CR+LF combinations in the compiled .go files. I don't know if that is what is happening here, but, I'll check that next time I have a chance.

You would unpack, configure, and build like you did before (with JIT

Once it has crashed, locate the =E2=80=98core=E2=80=99 file (or =E2=80=98co= re.*=E2=80=99), and run, say:

=C2=A0 gdb libguile/.libs/guile bootstrap/core

This won't work on cygwin. If you want a core dump, you should use the<= br> dumper tool, as described here

Or you can set error_start to gdb to get an interactive gdb session on erro= r.

Given that John said that compilation went fine with GUILE_JIT_THRESHOLD=-1, I think perhaps this problem may have been fixed in the past. My suspicions are that this issue is an ABI issue with lightening that could perhaps be reproduced by: git co https://gitlab.com/wingo/lightening cd lightening make -C tests test-native Of course any additional confirmation is useful and welcome!

I haven't been able to get guile to compile under Cygwin (just a compilation error I haven't had time to track down), but I was able to quickly try the above. I get: Testing: test-native-call_10 call_10.c:9: assertion failed: e == 4 /bin/sh: line 1: 7063 Aborted (core dumped) ./$test make: *** [Makefile:31: test-native] Error 134 Despite what it says about a core dump, I find no such thing. Just a file with the same name as the executable suffixed with ".stackdump". (I did attempt to configure the Cygwin dumper before running the tests.)

The x86 "fast-call" calling convention used on Windows x64[0] and shared by Cygwin[1] requires that the caller reserve 32 bytes of memory on the stack for the callee to spill the register parameters (even if the callee takes fewer than four parameters). I think lightening is currently missing that for the x64 case for Cygwin. To test the idea, I made a small modification (patch attached) that is *not* intended as a solution as it doesn't work for the general case, but it does allow the tests to pass on Cygwin 64.

The CPU_SETSIZE issue was what was hanging me up from compiling before Andy's comment got me to look at lightening. I assumed I had some configuration, package, or compiler issue. Good to know there's a simple fix. Just a further warning to anyone watching, that patch I posted is a real hack job just to test my theory of the cause of the segfault. I would expect it to fail when you have fewer than four arguments in a JITed function call. I wouldn't try doing much else with that Guile build besides run the tests. :) -- Charles From debbugs-submit-bounces@debbugs.gnu.org Mon Feb 17 14:27:48 2020 Received: (at 39118) by debbugs.gnu.org; 17 Feb 2020 19:27:49 +0000 Received: from localhost ([127.0.0.1]:39272 helo=debbugs.gnu.org) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1j3m3Y-0002a9-KI for submit@debbugs.gnu.org; Mon, 17 Feb 2020 14:27:48 -0500 Received: from relay11.mail.gandi.net ([217.70.178.231]:45501) by debbugs.gnu.org with esmtp (Exim 4.84_2) (envelope-from ) id 1j3m3V-0002a0-Rz for 39118@debbugs.gnu.org; Mon, 17 Feb 2020 14:27:46 -0500 Received: from mail-lj1-f181.google.com (mail-lj1-f181.google.com [209.85.208.181]) (Authenticated sender: charles@stanho.pe) by relay11.mail.gandi.net (Postfix) with ESMTPSA id 3ABD0100006 for <39118@debbugs.gnu.org>; Mon, 17 Feb 2020 19:27:43 +0000 (UTC) Received: by mail-lj1-f181.google.com with SMTP id w1so20131050ljh.5 for <39118@debbugs.gnu.org>; Mon, 17 Feb 2020 11:27:43 -0800 (PST) X-Gm-Message-State: APjAAAUtG+RotAk77V5YqNS30sxgGVXbu0U4Cxp5wkHH3/o2vlkOkmac xMXj6/wgxOawycVShFfsitRalnM36E96f8R7TT3njA== X-Google-Smtp-Source: APXvYqyW3MJTDlHa0kh+wbNc+P0zdj/Ck+HLyA8odgVqzcp37mOdmZF/Kd+57JKB1qBPP/OSPmrleohFQHjQaOeg528= X-Received: by 2002:a2e:95c4:: with SMTP id y4mr10704057ljh.38.1581967663325; Mon, 17 Feb 2020 11:27:43 -0800 (PST) MIME-Version: 1.0 Received: by 2002:ab3:6883:0:0:0:0:0 with HTTP; Mon, 17 Feb 2020 11:27:42 -0800 (PST) X-Originating-IP: [50.45.151.166] In-Reply-To: References: <87zherlphs.fsf@pobox.com> <875zh6gk72.fsf_-_@gnu.org> <20200120172253.GA1112065@spikycactus.com> <87wo90kmw9.fsf@pobox.com> <20200216232334.GA2448000@spikycactus.com> From: Charles Stanhope Date: Mon, 17 Feb 2020 11:27:42 -0800 X-Gmail-Original-Message-ID: Message-ID: Subject: Re: Segfault while building on 64-bit Cygwin To: Mike Gran Content-Type: multipart/mixed; boundary="0000000000009e8abe059eca8c53" X-Spam-Score: -0.7 (/) X-Debbugs-Envelope-To: 39118 Cc: Andy Wingo , 39118@debbugs.gnu.org, =?UTF-8?Q?Ludovic_Court=C3=A8s?= , John Cowan , guile-devel@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: -1.7 (-) --0000000000009e8abe059eca8c53 Content-Type: text/plain; charset="UTF-8" On 2/16/20, Charles Stanhope wrote: > On 2/16/20, Mike Gran wrote: >> >> I can confirm that Charles's patch, plus another one line patch >> to define CPU_SETSIZE, is enough to get Guile 3.0.x to build and run >> on my box.

I've attached a patch that is less horrible and more correct than my previous one. It reserves the stack space regardless of the number of parameters and appears to work. But I'm new to the lightening code base, so I'm not convinced it is the correct solution. It's just the solution I was left with after my time ran out. I wanted to post this patch as a replacement to the prior one in case people did want to do more testing with Guile 3.0 on Cygwin x64. With that, I will let more experienced people come up with the appropriate solution.
