3289,boost::phoenix::lambda doesnt handle local variables very well.,kuentang@…,Joel de Guzman,"Introducing a local variable in boost::phoenix::lambda without using an argument names create a compiler error with boost 1.40 and msvc 2008. To be precise: The code

double abc=lambda(_a=*ref(it)++)[_a*2.0]()(); // here 'it' is an //iterator

create a boost::phoenix::detail::error_expecting_arguments error. The problem seems to be connected to the no_nullary. the following code reproduce the error:

# include <algorithm>
# include <vector>

# include <boost/spirit/include/phoenix.hpp>

using namespace boost::phoenix;
using namespace boost::phoenix::arg_names;
using namespace boost::phoenix::local_names;

int main()
{

    std::vector<double> u(11,1.0);
    std::vector<double> w(11,2.0);
    std::vector<double>::const_iterator it=w.begin();
    //boost::phoenix::generate(ref(u)
    //    ,lambda(_a=*ref(it)++)[_a*2.0 ]
    //)();

    double abc=lambda(_a=*ref(it)++)[_a*2.0]()();
    return 0;
