Comment (by julian):

 >(if it is the same crash which I don't know)

 i'm quite sure, its also in ff_ass_split_override_codes(). will test with
 this file too once a fix is available to confirm.

 >(A crash does not get less important if it is difficult to trigger as
 long as there is a sample that triggers the crash.)

 ok thanks. i believed so, thats why i mentioned it. i guessed if the crash
 occurred /only/ in some obscure asiatic subtitles which are hard to come
 by it would be low priority ...

 at least we know its not related to a specific language now.
