That surely suggests a problem in the font, and xetex is probably
tripping over the same thing.
Of course, xetex shouldn't crash even if a font is damaged, but the
low-level opentype code in ICU doesn't always check thoroughly for
bad font data. (That may be a deliberate choice in the interests of
efficiency, I suppose.)
It may be that I can make the code more robust, if I can find time to
look into exactly where and why the failure happens, but the real
solution is to fix the font.
