Still happens, though much more rarely than before.  No sure way to
reproduce, but in this short source code file:

#include "engine/strategy/evaluation/material.hpp"

#include <utility>


using namespace engine;

using namespace std;


int
MaterialEvaluationFunction::do_evaluate_material (Board::PackedMaterialData material)
{
  const int  score            = _algorithm->evaluate (material);
  const int  normalized_score = ((score * get_first_rabbit_value ())
                                 / _algorithm->get_first_rabbit_value ());

_cache.insert (make_pair (material, normalized_score));
}

I'm getting wrongly indented '_cache.insert ...' line.  C-c C-s on it
also shows 'topmost-intro'.  I guess this heavily depends on the order
in which code is typed.

After I killed the buffer and reopened it, indentation is back to
normal and C-c C-s on that line correctly shows 'statement'.
