[XeTeX] CID-keyed font support?

[Akira Kakuto]

Hi Khaled, Jiang,

> I cannot find the location where the crash occurs.

If I remove
pdf_close_fonts ();
in pdf_close_document (void) in pdfdoc.c,
the crash disappears, of course the resulting pdf is bad.
Thus I believe pdf_close_fonts() in pdffont.c must be
the reason of the crash on Windows.

Best,
Akira
