C++11 empty initializer lists seem to cause a parsing problem. Consider:

// not parsed correctly by doxygen 1.8.5
class X
{
public:
  typedef std::initializer_list<double> DoublesInitializer;
  typedef std::initializer_list<int   >    IntsInitializer;

  X(DoublesInitializer d, IntsInitializer i={}) : d_(d), i_(i) {}
  X(IntsInitializer i) : X({},i) {}

private:
  const std::list<double> d_;
  const std::list<int   > i_;
};

In the Doxygen html output there appear superfluous „Public Attributes” i and i_, the first without a type, and the second with type const std::list<int>. Doxygen also believes to find „Initial value” for i, which is

{}

private:
  const std::list<double> d_

It turns out that the second constructor is the problematic one, since this works correctly:

// parsed correctly by doxygen 1.8.5
class Y
{
public:
  typedef std::initializer_list<double> DoublesInitializer;
  typedef std::initializer_list<int   >    IntsInitializer;

  Y(DoublesInitializer d, IntsInitializer i={}) : d_(d), i_(i) {}
  Y(IntsInitializer i) : Y(DoublesInitializer(),i) {}

private:
  const std::list<double> d_;
  const std::list<int   > i_;
};
