What you're seeing is bug#872 (also #1179). I originally thought it depended on `display-unibyte-via-language-environment', but it is not so; I've seen it (and suffered it) through several different incarnations. What they all have in common: - Using a "recent" MinGW GCC (4.2.1, 4.3.0-alpha, etc.) - Compiling with optimization - Trying to display unibyte (or, perhaps, some composed characters, I'm not sure) - It *always* happens when draw_glyphs is running - It mostly happens in fill_glyph_string I can reproduce it at will in a lot of ways, for example: M-x ucs-insert AEGEAN CHECK MARK or (let ((my-map (make-keymap))) (suppress-keymap my-map) (substitute-command-keys "\\{my-map}")) or having `display-unibyte-via-language-environment' set to t and `debug' being called for whatever reason, etc. etc. I've been trying to debug it, without success (it doesn't help that I know very little about the glyph handling code). I'm not even sure whether it is a compiler bug, or a bug in Emacs (it happens in code that was undergoing changes quite recently).

Is it a Heisenbug? i.e., does it disappear if you add printf's around the code that crashes or in its callers? If the bug stays put when code around it is modified, you could try debugging it by adding "if (something) abort ();" lines testing various conditions that are suspect of causing the crash. Some observations based on the traceback posted by Feng Li: > Program received signal SIGSEGV, Segmentation fault. > 0x0101fdd5 in fill_glyph_string (s=0x820000, face_id=27, start=, end=, overlaps=) at xdisp.c:19740 Line 19740 in xdisp.c is this: s->ybase += voffset; And "bt full" says this about `s': > s = (struct glyph_string *) 0x0 However, `s' is dereferenced many times in `fill_glyph_string' before it gets to line 19740, so I think GDB lies about the place where it crashed (because GCC optimizes code to the degree that any relation between the code and the source lines is lost). Therefore, the first thing to do is disassembly the vicinity of the crash locus (0x0101fdd5) and see which code, exactly, crashes, and why. Disassembly should establish (1) the source line that crashes, and (2) which C-level variable causes the crash. Note that `s' is allocated via `alloca' in BUILD_CHAR_GLYPH_STRINGS, which is called by BUILD_GLYPH_STRINGS, which in turn is called by `draw_glyphs' at line 20332 in frame #1: > #1 0x01040a0c in draw_glyphs (w=0x3439800, x=72, row=0x3345260, area=TEXT_AREA, start=0, end=30, hl=DRAW_NORMAL_TEXT, overlaps=0) at xdisp.c:20332 The original source line 20332 in xdisp.c looks like this: BUILD_GLYPH_STRINGS (i, end, head, tail, hl, x, last_x); From lekktu@gmail.com Fri Nov 28 03:23:37 2008 X-Spam-Checker-Version: SpamAssassin 3.2.3-bugs.debian.org_2005_01_02 (2007-08-08) on rzlab.ucr.edu X-Spam-Level: X-Spam-Status: No, score=-5.6 required=4.0 tests=AWL,BAYES_00,HAS_BUG_NUMBER, IMPRONONCABLE_2 autolearn=ham version=3.2.3-bugs.debian.org_2005_01_02 Received: (at 1448) by emacsbugs.donarmstrong.com; 28 Nov 2008 11:23:37 +0000 Received: from an-out-0708.google.com (an-out-0708.google.com [209.85.132.242]) by rzlab.ucr.edu (8.13.8/8.13.8/Debian-3) with ESMTP id mASBNYOf028589 for <1448@emacsbugs.donarmstrong.com>; Fri, 28 Nov 2008 03:23:35 -0800 Received: by an-out-0708.google.com with SMTP id c38so512827ana.31 for <1448@emacsbugs.donarmstrong.com>; Fri, 28 Nov 2008 03:23:33 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=gamma; h=domainkey-signature:received:received:message-id:date:from:to :subject:cc:in-reply-to:mime-version:content-type :content-transfer-encoding:content-disposition:references; bh=FJlcvnU07kAJV2YKZr8YdHLF3XHWpJUUP7O0V8bmd3c=; b=VZXAAoRrU8z22M6VM/ZhwzwiUUyccA0HUiHoEWbsxWrfVNF44OgULiF+v7C9fGlq3H UicnYn5ckfI6WIZnEIuymIe/7U0XLTyn5267qo/0GfxHc4O6RzGG+LAEr2KpyfuJwUhZ 9n67nKWgGqEKYM2DZpBCt6MwwLSx3yidymKCI= DomainKey-Signature: a=rsa-sha1; c=nofws; d=gmail.com; s=gamma; h=message-id:date:from:to:subject:cc:in-reply-to:mime-version :content-type:content-transfer-encoding:content-disposition :references; b=IpsEkWIJo4aME5CUJQ3f/Hv+mWx+vN3TXI2hOfWSG/fVL7K9ADVNIhS2mgdq1CwLAD xuU8Sv+WL9H8ftG1jvxDnrKE0ljxG/kIsDMNgkq44+M3CU2cdf2wiUDaoIBhKNXy2s9o 3wVrIrmQd6xAQDtAKLDLgRYpiZzGo9UTh33f8= Received: by 10.100.153.4 with SMTP id a4mr4049445ane.101.1227871413761; Fri, 28 Nov 2008 03:23:33 -0800 (PST) Received: by 10.100.13.13 with HTTP; Fri, 28 Nov 2008 03:23:33 -0800 (PST) Message-ID: Date: Fri, 28 Nov 2008 12:23:33 +0100 From: "Juanma Barranquero" To: "Eli Zaretskii" Subject: Re: bug#1448: 23.0.60; update to cvs emacs crash report Cc: 1448@debbugs.gnu.org, "Feng li" In-Reply-To: MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 7bit Content-Disposition: inline References: <81hc5s5t2y.fsf@blackmagic-design.com> On Fri, Nov 28, 2008 at 11:56, Eli Zaretskii wrote: > How does "C-h b" get to display unibyte or composed characters?

Not exactly a heisenbug, because it does not disappear. It moves. That's why I've said that it always fails with draw_glyphs in the stack, but not always in fill_glyph_string. > If the bug stays put when code around it is modified, you could try > debugging it by adding "if (something) abort ();" lines testing > various conditions that are suspect of causing the crash. I've tried that (well, I added xassert() and/or eassert) at likely places; they didn't get triggered. > However, `s' is dereferenced many times in `fill_glyph_string' before > it gets to line 19740, so I think GDB lies about the place where it > crashed (because GCC optimizes code to the degree that any relation > between the code and the source lines is lost).

It also started suddenly for me, after some big changes related (I think) to character composition. But that does not mean that it could not be a compiler bug: perhaps the new code triggers the bug, and the old code didn't. That said, my gut feeling is that is not a compiler bug because I'm getting it with two compilers, 4.2.1 and 4.3.0, but it is not impossible that such a bug, if it is specific to the MinGW port, could go undetected between releases.
