OK.  I get the impression this is VERY annoying, but that it happens very
frequently rather than just now and then.  Good!

I'm assuming your Emacs is pretty much the newest bzr version.

Would you please choose a C file, as small as will work, and start an
Emacs session with a dribble file (see page "Recording Input" in the
Elisp manual).  Edit the C file until indentation goes wrong.  Then send
me the dribble file, the (original) C file, and your CC Mode
configuration (generated by C-c C-b in the C file).

Apologies for this horrible bug, and thanks for you help in nailing it
