I suspect not, but who knows?  :-(

However, I can reproduce this bug; the dribble file and your CC Mode
configuration file were utterly essential to my doing so.  Thanks!

Yes.

No, that's not it.  In the course of creating this file, as per your
dribble, some "text properties" (deep in the bowels of CC Mode) are being
spuriously applied to certain characters in the buffer.  I'll track down
exactly which keystroke provoked this, and hopefully be able to fix it
sometime soonish.

Thanks for taking all this trouble to help me reproduce the bug.
