[Boost-users] lexical_cast and infinity

The last line of the following program throws a bad_lexical_cast exception. The
code is compiled with VC7.1.

//**********************************************************
#include <limits>
#include <iostream>
#include <boost/lexical_cast.hpp>

int main(int argc, char* argv[])
{
    double d = std::numeric_limits<double>::infinity();
    std::string s = boost::lexical_cast<std::string>(d);
    std::cout<<d<<", "<<s<<std::endl;

    //Throws bad_lexical_cast
    boost::lexical_cast<double>(s);
}
//**********************************************************

The output is:

"1.#INF, 1.#INF"

Am I doing something wrong ?
