The ChangeLog entry does mention the specific change explicitly:
Ah. Still kind of cryptic, though. _Why_ shouldn't they be used?
Well, not entirely cryptic - seems to be a rewrite with an 'enhanced bitmap
loader' for the changes in the same group.

...
* 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?
Honestly, I have been able to trigger the crash myself. It appears to
be triggered by a certain font (or set of fonts). The Microsoft
webfonts seem to be particularly problematic.
I have the microsoft fonts, actually, and I just changed mozilla-xft to use
specifically courier new (the one in your gdb backtrace) for display. No
crashes yet. Granted, mozilla-xft probably used it differently - *how* do you
trigger a crash? You do realise the font name is quite broken (seems to be
followed by garbage all the time) in your gdb bt?
"-webfonts-courier new-medium..."
may worth checking your font.dir - seems to be hand-edited - mine
is auto-generated by mkfontdir, and entry start with e.g.
"-microsoft-courier new-..."

Yes, there must be a reason, but that commit message doesn't list
sfdriver.c explicitly. That's why I was wondering what the exact reason
was for the change, and what new steps should be done to get similar
results from FT.
