This is standard operation of the Emacs C mode: some characters,
including the left parenthesis, are "electric", in that they invoke
reindentation/reformatting of the current line.  Type "C-h k (" to see
the documentation of that, including links to customization options,
which you can tweak if you don't like the default behavior.

IOW, I don't think this is a bug at all, but intended behavior.

Thanks.

P.S. Please don't cross-post to emacs-devel and the bug list.
