Apologies: Now that I've committed a wodge of CC Mode bug fixes, I'm
hoping to much less "busy" from now on.

I've just fixed a bug very similar to this, in which a comment ending in
"=======*/" got rubbed out.

The problem with the current bug (in the latest cc-engine.el) is that
c-mask-paragraph assumes that a c-style comment is terminated (with
"*/"), doing this at one point:

(search-forward-regexp (concat "\\=[ \t]*\\("
 		        c-current-comment-prefix "\\)")
		       (- (cdr c-lit-limits) 2) t)
		        ^^^^^^^^^^^^^^^^^^^^^^^^^^

Clearly this is nonsense if the comment hasn't been terminated yet.

I'll fix this (hopefully) tomorrow.
 
Happy 2007!
