BTW I reproduced using the reported test case:

#include <sigc++/sigc++.h>

#if __cplusplus >= 201100L || defined (__GXX_EXPERIMENTAL_CXX0X__)
#include <type_traits>

namespace sigc
{
    template <typename Functor>
      struct functor_trait<Functor, false>
      {
        typedef decltype (::sigc::mem_fun(std::declval<Functor&>(),
&Functor::operator())) _intermediate;
        typedef typename _intermediate::result_type result_type;
        typedef Functor functor_type;
      };
}
#endif


int main()
{
  sigc::slot <bool> slot3 = [] () -> bool { return true; };
  sigc::slot <bool, int> slot4 = [] (int) -> bool { return true; };
  while (1);
}


and building it on Fedora 16 with

g++ -std=c++0x -g -o pr pr.cc $(pkg-config --cflags sigc++-2.0) $(pkg-config
--libs sigc++-2.0)

Simplest way to see it is "gdb -readnow pr"
