[Devel] FreeType 2.1.3 segfaults with htst3.ttf

[Anthony Fok]

Hello,

While I was trying to evaluate a Chinese TrueType font--HuaTian
Three-step complex TTF song font (GB2312)--which, moreso than MingLiU,
uses bytecode instructions to shape the strokes and even components of
Chinese characters (is it the same as "recursive composite" that Owen
referred to recently?)  The sample font is available for download here:

        http://www.htit.com/english/downloads.htm
        http://www.htit.com/download/htst3.ttf

I was able to view this font with ftview1 (freetype 1.3.1) without any
problem, but with ftview from freetype-2.1.3, a segmentation fault
would usually occur when a Chinese character is about to be rendered
(glyph 780 and on). However, I have to admit that It is beyond my skill
to debug this.  :-)

I have attached two gdb backtraces for reference.

Cheers,

Anthony
