[Fontconfig] Re: Committed mmap patch to branch

I gave this a test (w/o actually installing it yet).  

Running the uninstalled fc-cache (via the libtool script, of course)
resulted in a segv:

(gdb) where
#0  0xb7d7f968 in strcmp () from /lib/tls/libc.so.6
#1  0xb7f271ae in FcCacheSkipToArch () from /home/cloos/Projects/FC/TAGS/fc-2_4_branch/src/.libs/libfontconfig.so.1
#2  0xb7f27721 in FcGlobalCacheSave () from /home/cloos/Projects/FC/TAGS/fc-2_4_branch/src/.libs/libfontconfig.so.1
#3  0xb7f2b294 in FcConfigBuildFonts () from /home/cloos/Projects/FC/TAGS/fc-2_4_branch/src/.libs/libfontconfig.so.1
#4  0xb7f3227c in FcInitLoadConfigAndFonts () from /home/cloos/Projects/FC/TAGS/fc-2_4_branch/src/.libs/libfontconfig.so.1
#5  0xb7f324ec in FcInit () from /home/cloos/Projects/FC/TAGS/fc-2_4_branch/src/.libs/libfontconfig.so.1
#6  0x0804923a in main ()

It also seemed to ignore the directory I supplied on the command line
and scanned through all of the <dir/>s in my fonts.conf, mmap(2)ing
each font.  (I only followed along via strace(1); I didn't step thru
in gdb(1).)

I used the -v option, and the segv occurred before anything was output.

The dump above was w/ -v but w/o other args.
