unicode-2 branch segfaulting on MacOS X?

unicode-2 branch segfaulting on MacOS X?

[Geoffrey Alan Washburn]

I've been trying to get the latest revision of the emacs-unicode-2 
branch to build and run under MacOS X.  Building seems to work fine, 
I've been using the following configuration

./configure --prefix=/local --enable-font-backend --with-gtk --with-xft 
--with-tiff --with-ungif --with-xpm --enable-asserts CPPFLAGS=-idirafter 
/usr/X11R6/include

However, when I attempt to invoke emacs with

emacs --enable-font-backend --font "Bitstream Vera Sans Mono-16"

it seems to be segfaulting somewhere in font_unparse_fcname.  Any ideas?

I can't reproduce it on GNU/Linux.  So, could you please use
gdb to find exactly where (and how) Emacs causes segfault
(see etc/DEBUG if you are not familiar with gdb).

	Indeed, the same version works fine on my ThinkPad running Debian 
GNU/Linux.

	Could you be more specific about what you mean by "how" it is 
segfaulting?  It is pretty obvious that it is reading/writing an invalid 
memory location.  As I said the problem occurs in font_unparse_fcname. 
In particular, line 1258 of font.c with parameters font=42759700, 
pixel_size=19, name=0x2a20d20 "", and nbytes=96.

That's what I wanted to know.  The code around line 1258 is
this:

1255  val = AREF (font, FONT_FOUNDRY_INDEX);
1256  if (! NILP (val))
1257    /* ":foundry=NAME" */
1258    len += 9 + SBYTES (SYMBOL_NAME (val));

So the variable `val' is suspicious.  Please check the type
and value of `val' as this:

(gdb) p val
(gdb) xtype
(gdb) pp val

(gdb) p val

(gdb) xtype

(gdb) pp val

Thank you.  It seems val contains completely broken value.
Please show me the result of these commands:

(gdb) pp font
(gdb) bt full

Thank you.  Now the result is meaningful.

Hmmm, this means that your "bitstream vera sans mono" font
doesn't have FC_WIDTH property.  Very strange.  What does
this command return?

% fc-list 'bitstream vera sans mon' width

Anyway, I've just installed a workaround for such a case.

	Strange, it just returned a blank line.  After deleting the Bitstream 
fontconfig cache file and rebuilding with "sudo fc-cache", this fixed 
problems as far as fc-list was concerned.

% fc-list fc-list 'bitstream vera sans mono' width
:width=100

However, emacs is still reporting that it is getting an empty string for 
the width property. That is, your new error message

peculiar error: "invalid font property", (:width . "")

FWIW, it doesn't return anything here:

% fc-list 'bitstream vera sans mon' width
% fc-list 'bitstream vera sans mon' width | hd
% 

This is a clean install of the FreeBSD package of bitstream-vera:

% pkg_info | grep bitstream-vera  
bitstream-vera-1.10_2 Bitstream Vera TrueType font collection
%

But rebuilding the fc-cache now returns:

% fc-list 'bitstream vera sans mono' width
:width=100
%

Hmmm :)

	Yes, doing the same worked for me.  At least with regards to 'fc-list'. 
  The latest emacs-unicode-2 (at least as of yesterday morning) was 
still not seeing the width attribute even though 'fc-list' now does. 
However, thinking about it now, it is quite likely that I have multiple 
versions of 'fc-list' installed on my computer, so maybe I should query 
them all to see if somehow the fontconfig library emacs is being linked 
against isn't still confused.

	After some additional research I determined that the system installed 
version of fontconfig did not seem to handle the width attribute 
properly, but the Darwin Ports install of fontconfig did.  So after some 
futzing with CPPFLAGS, LDFLAGS, and DYLD_LIBRARY_PATH when running 
configure, I was able to finally get emacs-unicode-2 running without any 
apparent problems.

	So if anyone else happens to have this problem, make sure the version 
of fontconfig you're linking against on MacOS X isn't broken.

Please check which libfontconfig is used by emacs and
fc-list.  Does this work on Mac OS?

% ldd THE_ABSOLUTE_PATH_OF_EMACS_BINARY | grep fontconfig
% ldd THE_ABSOLUTE_PATH_OF_FC_LIST_BINARY | grep fontconfig

	Alas MacOS X doesn't have something exactly equivalent to ldd (or I 
haven't been able to figure it out).  There are some environment 
variables that can be set to print out what dynamic libraries it loads.
As I mentioned in my other e-mail I have figured out that it was indeed 
a problem with emacs linking against Apple's X11 libraries rather the 
Darwin Ports version of fontconfig.

otool -L should do the trick.

Did you find a way to link Emacs with the proper version of
fontconfig?  If so, did it solve the current problem?

Yes, I had written a post to the list about this about a week ago. 
Thanks again for your help.
