From: Simon Leinen <simon.leinen <at> switch.ch> To: <bug-gnu-emacs <at> gnu.org> Subject: 27.0.50; Mac OS/Lucid/X11: crash with libharfbuzz Date: Mon, 22 Jul 2019 09:09:21 +0200
I regularly build Emacs from Git master on my work system, an Apple
laptop running Mac OS 10.14.5 "Mojave". My current binaries have been
built from commit fd5410217ff23810edc16e97c10934ad622f8e4b.
As I want to use open standards as far as possible, I've always been
building with X11 libraries (--with-x --with-x-toolkit=lucid
--with-ns=no).
Lately I have experienced several crashes, mostly while using GNUS
(which fontifies articles in interesting ways). From running under the
debugger, it seems they are related to libharfbuzz in some way.
Unfortunately I have no easy way to reproduce this from emacs -Q.
I haven't yet been able to work around Mac OS's security restrictions
enough to run Emacs under GDB. But I've been running it under Apple's
"lldb" debugger and was able to create a backtrace:

Could you try the following instructions?
1. recompile Emacs with CFLAGS="-O0 -g3"
2. run it under lldb.
3. run GNUS and wait for crash happens.
4. repeat lldb "up" command until it reaches emacs`ftfont_list
(frame #12 in the original stack trace)
5. run "p file" under lldb.

Thanks. I rather suspect it has something to do with the versions of
Harbuzz. Could you try to see if the following test program crash on
your side?
/* cc -g hb-ot-test.c `pkg-config freetype2 harfbuzz --cflags --libs` */
#include <stdio.h>
#include <ft2build.h>
#include <freetype/freetype.h>
#include <hb.h>
#include <hb-ft.h>
#include <hb-ot.h>
int
main ()
{
printf ("HarfBuzz Version: %s\n", hb_version_string ());
static FT_Library ft_library;
FT_Init_FreeType (&ft_library);
FT_Face ft_face;
FT_New_Face (ft_library, "/System/Library/Fonts/ArabicUIDisplay.ttc", 0,
&ft_face);
hb_face_t *face = hb_ft_face_create_referenced (ft_face);
FT_Done_Face (ft_face);
unsigned int script_count
= hb_ot_layout_table_get_script_tags (face, HB_OT_TAG_GSUB, 0, NULL, NULL);
printf ("GSUB script_count = %d\n", script_count);
script_count
= hb_ot_layout_table_get_script_tags (face, HB_OT_TAG_GPOS, 0, NULL, NULL);
printf ("GPOS script_count = %d\n", script_count);
}
On macOS 10.14.6 Beta, I could successfully run it with the following
output:
HarfBuzz Version: 2.5.3
GSUB script_count = 1
GPOS script_count = 1

No, that runs fine (return code 0) and outputs
HarfBuzz Version: 2.5.3
GSUB script_count = 1
GPOS script_count = 1

What happens if you link the test program with the latter one using the environment variable DYLD_LIBRARY_PATH ? $ DYLD_LIBRARY_PATH=/opt/X11/lib ./a.out YAMAMOTO Mitsuharu mituharu <at> math.s.chiba-u.ac.jp

Ah, good point - I hadn't noticed that!

Unfortunately it is not that easy:
: leinen <at> macsl[tmp]; DYLD_LIBRARY_PATH=/opt/X11/lib ./a.out
dyld: Library not loaded: /usr/local/opt/freetype/lib/libfreetype.6.dylib
Referenced from: /private/var/tmp/./a.out
Reason: Incompatible library version: a.out requires version 24.0.0 or later, but libfreetype.6.dylib provides version 19.0.0
Abort trap: 6
...but if I recompile the test program with -L/opt/X11/lib, then it
crashes:
: leinen <at> macsl[tmp]; cc -g hb-ot-test.c -L/opt/X11/lib `pkg-config freetype2 harfbuzz --cflags --libs`
: leinen <at> macsl[tmp]; objdump -macho -dylibs-used /var/tmp/a.out
/var/tmp/a.out:
/opt/X11/lib/libfreetype.6.dylib (compatibility version 19.0.0, current version 19.6.0)
/usr/local/opt/harfbuzz/lib/libharfbuzz.0.dylib (compatibility version 20504.0.0, current version 20504.0.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.250.1)
: leinen <at> macsl[tmp]; ./a.out
HarfBuzz Version: 2.5.3
Segmentation fault: 11
So I guess all I have to do is make sure Emacs doesn't use the old
libfreetype in /opt/X11/lib, but rather the newer one in /usr/local/lib
(and hope that that one works in an X11 environment...)
I'll be in meetings for the next few hours, but will let you know what
happens once I find time to do the above.
Thanks a lot so far!!!
Cheers,

I finally managed to get the Emacs Makefiles put -L/usr/local/opt/freetype/lib in front of -L/opt/X11/lib, and rebuilt my Emacs binaries. They now no longer crash when I open the message with the Arabic font in GNUS. Hooray! So the problem was a typical "DLL hell" issue that I brought upon myself by selecting an unusual combination of libraries. I don't think there's much for the Emacs developers to improve in this situation. Therefore I think this bug can safely be closed. I wrote up my (fixed) build procedure on my blog: https://blog.simon.leinen.ch/2019/07/compiling-emacs-on-mac-os-against-x11.html This is mainly for my own reference - it's so convoluted that I rely on config.log to reconstruct all the options... but the Internet is big, and maybe it's even useful for someone else. Thanks again for your kind help with this! Best regards, -- Simon.

For future reference, FreeType 2.7.0 bundled with XQuartz 2.7.11 crashes if used with HarfBuzz 2.5.3, but FreeType 2.10.1 doesn't. YAMAMOTO Mitsuharu mituharu <at> math.s.chiba-u.ac.jp
