Mostly in C++ Mode, with usually with quite complicated code
(templates), but not only.  E.g. I lost patience with it on a file
without templates where only more or less non-common thing was a local
namespace.  It looks basically like this (using my preferred
indentation style, might be important):

namespace
{
  class Foo : public Bar
  {
  public:

    virtual  void
    bla_bla (some_type& x, const string& y)
    {
      ...
    }

    ...
  };
}

It used to break heavily in such functions (there are many similar)
inside a local class.  Function names were becoming colored with
'font-lock-variable-name-face' and as such indented wrongly.

OK, but a bit later.  I guess it is of little help, but currently I
use revision 98816 (just chose one at random) and cc-mode works fine.
