6343,Spirit::qi semantic action destroys attribute value,kkanishev@…,Joel de Guzman,"Long story short. This code:
{{{
#include <boost/config/warning_disable.hpp>
#include <boost/spirit/include/qi.hpp>
#include <boost/foreach.hpp>

#include <iostream>
#include <string>
#include <vector>

void f(){return;}

int main()
{
        namespace qi = boost::spirit::qi;
        namespace ns = boost::spirit::ascii;

        qi::rule<std::string::iterator,std::vector<int>(),ns::space_type>  ex;
        ex =  qi::int_[f] >> *ex;

        std::string str = ""3 1 4 1 5 9"";
        std::vector<int> out;

        if(qi::phrase_parse(str.begin(),str.end(),ex,ns::space,out))
        {
                std::cout << ""Result: "";
                BOOST_FOREACH(int d , out) std::cout << d << "" , "";
                std::cout << ""\n"";
        }
}
}}}
Doesn't change the contents of the ""std::vector<int> out"".

If I remove the semantic action:
{{{  ex =  qi::int_ >> *ex; }}}

Then everything goes as expected.",Bugs,closed,To Be Determined,spirit,Boost 1.48.0,Problem,invalid,,
