As I said earlier, I think it more likely these changes in CC Mode have
triggered a bug rather than being buggy themselves. (OK, anybody, feel
free to demolish my hubris ;-) I haven't looked into it much, but it
seems likely that the syntax.c stuff for a Unicode branch will have been
enhanced to cope with the wierdnesses of that character set.
Could you please run edebug[*] on c-beginning-of-current-token, and check
that the arguments which are passed to skip-syntax-backwards are valid.
If they're not, it's CC Mode's problem. If they are, let's wait and see
what Stefan says.
[*] If you're not familiar with Edebug, it's well described in the Elisp
manual. Send me a private email if you want help to use it.
