Subject: 24.4.51; Error using mark-defun in c++-mode

From: Ivan Andrus <[email-masked]>

Starting from emacs -Q, create a buffer in `c++-mode' with contents below.

class Bob
{
protected:

    void fun()
    {
    }

};

Placing point on the line after "protected:" and running mark-defun gives
the error:

c-where-wrt-brace-construct: c-where-wrt-brace-construct: c-beginning-of-decl-1 returned label

Ideally it would give no error, and IMO, it should mark fun(), though marking the class would be fine as well.
