The ChangeLog entry does mention the specific change explicitly:
2005-02-28 David Turner <david@freetype.org>
...
* src/sfnt/sfdriver.c (sfnt_interface)
[TT_CONFIG_OPTION_EMBEDDED_BITMAPS]: Don't use `tt_find_sbit_image'
and `tt_load_sbit_metrics'.
...
So the change is intentional. I just upgraded to stock freetype 2.1.10
(was using cvs-2004-dec-31), went around a few web pages with mozilla-xft,
and I don't have crashes. I am using xorg 6.8.2 on linux. How do you
trigger the crash?
