#11475: qi real parser- valgrind error
------------------------------+---------------------
 Reporter:  oswin.krause@…    |      Owner:  djowel
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  spirit
  Version:  Boost 1.59.0      |   Severity:  Problem
 Keywords:  valgrind          |
------------------------------+---------------------
 I tested boost 1.59 rc1 today and got a regression in my software. my csv
 parser reported 4 wrong values (of approximately 200)

 i reduced the problem somewhat to

 {{{
 #include <boost/spirit/include/qi.hpp>
 #include <vector>
 #include <string>
 #include <iostream>
 using namespace boost::spirit::qi;
 int main(){
         std::cout<<BOOST_LIB_VERSION<<std::endl;
         std::string str="1.0,119,80,35,0,29.0,0.263,29,1";
         std::vector<double> fileContents;
         phrase_parse(
                 str.begin(),str.end(),
                         double_ % ',',
                 space , fileContents
         );

         for(std::size_t j = 0; j != 9; ++j)
                 std::cout<<fileContents[j]<<" "<<std::flush;

 }

 }}}

 problems vanish in debug mode, g++ finds a warning and valgrind finds a
 conditioned jump based on unitialised memory. see attached the outputs for
 comparison
