13536	"boost::lexical_cast<int>("" 1 "") can no longer handle whitespace"	maxim.egorushkin@…	Antony Polukhin	"boost::lexical_cast can no longer handle whitespace when converting strings to integers:

{{{
    #include <string>
    #include <iostream>
    #include <boost/lexical_cast.hpp>

    int main() {
        auto i = boost::lexical_cast<int>("" 1 "");
        std::cout << i << '\n';
    }
}}}

The above incorrectly throws an exception. 

The correct result of boost::lexical_cast<int>("" 1 "") is `1` and no exception.

At least boost version 1.54 did not have this problem."	Bugs	closed	To Be Determined	lexical_cast	Boost 1.61.0	Showstopper	wontfix
