qi real parser- valgrind error

[oswin.krause@…]

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

Sorry for the duplicate ticket. I have got troubles uploading the files, Track rejects it as spam as it is including blacklisted patterns...help?
