Hi Khaled,
I can not reproduce the crash here, so I'll leave it to Jiang to comment.
After some tests, I found the following: It depends on the type of Japanese font used. (1) Not embed Japanese font There is no crash. The resulting PDF is fine. (2) Embed TrueType Japanese font There is no crash. The resulting PDF is fine. (3) Embed OpenType Japanese font The crash occurs. I suspect your case is (1) or (2). In the case of (3), font->used_glyphs, a new data introduced by Jiang, may be broken. Best, Akira -------------------------------------------------- Subscriptions, Archive, and List information, etc.: http://tug.org/mailman/listinfo/xetex
