Hello Keith,
While doing some testing with Firefly's fix for mixed AA and non-AA
patch (which I think you fixed already, but not yet in XFree86 4.3.0
etc. and thus not yet propagated to most distributions), I tried to
reproduce the problem on Debian (unstable/sid), and move the Arial and
Verdana TrueType fonts out of the way so I could have only the bitmap
helvetica left. After that, "xfd -fa arial-24" segfaults. It is
likely triggered by a dangling symlink.
In /etc/fonts/fonts.conf:
<dir>/usr/share/fonts</dir>
<dir>/var/lib/defoma/x-ttcidfont-conf.d/dirs</dir>
/usr/share/fonts/truetype/Arial.ttf:
Actual font file
/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType/Arial.ttf:
Symlink to /usr/share/fonts/truetype/Arial.ttf
(Yes, that's the design of defoma Debian Font Manager.)
Not sure if it matters: I don't have
/usr/share/fonts/truetype/fonts.cache-1
Steps to reproduce:
1. Just to make sure everything is in a clean state, I removed
~/.fonts.cache-1.
2. "xfd -fa arial-24" works fine.
3. Move /usr/share/fonts/truetype/Arial.ttf out of the way.
4. "xfd -fa arial-24" now shows error:
Warning: Cannot convert string "arial-24" to type XftFont
Segmentation fault
At this point, ~/.fonts.cache-1 was automatically updated with the
"/usr/share/fonts/truetype/Arial.ttf" entry removed, but the entry for
"/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType/Arial.ttf" still
lingers, which is okay, I suppose. :-)
XftFontClose() is called twice though: (I installed your latest
render-0.8, xrender-0.8.2 and xft-2.1.2 in /tmp/dest)
$ LD_LIBRARY_PATH=/tmp/dest/usr/X11R6/lib gdb --args ~/xfd -fa arial-24
...
(gdb) bt

The xftfreetype.c here is from xft-2.1.2.
Thanks in advance!
Cheers,
Anthony
P.S. I know I probably should use bugzilla, but I'm too sleepy now, and
I'll probably forget to report it if I don't do it now, so... :-)
