[Devel] Segfault at FT_New_Face() for some Type1 fonts?

[Anthony Fok]

Hello all,

I just received two bug reports from the Debian Bug Tracking System.
It seems that FreeType 2.0.5 would segfault at FT_New_Face() or other
functions for some Type1 fonts.  (It was originally thought to be
a gnome-print problem, but apparently ftview exhibits the same error.)
(I wonder if it is a known problem or not.)

BTW, Andras and Mike, if possible, could you please send me a copy of
a font that triggers this error, and as well as the {l,s}trace? 
Thanks!  I am sure the FreeType developers would like to test it
too.  :-)

For more information, please refer to these two pages:

        http://bugs.debian.org/119848
        http://bugs.debian.org/122485

One case looks like this:
