I've verified this problem with 5.25, and also that it's gone in 5.27
(the latest release). So I suggest you upgrade; it's available for
download from http://cc-mode.sourceforge.net/. This particular bug
aside, I can say that the line break and text filling routines
underwent a major rewrite in 5.26; they're quite a lot better now.
