 After change

 SVN changelist 80291 (git commit 5ce9c1e41909537371a526bd2e951ff1466eeb9a)

 coupling lexical_cast with std::transform in the way

 std::transform(vector.begin(), vector.end(), str_list.begin(),
 boost::lexical_cast<string, double>);

 is not working because lexical_cast is overloaded. Compilation error is

 base_helper.cpp:25:5: error: no matching function for call to 'transform'
     std::transform(vector.begin(), vector.end(), str_list.begin(),
 boost::lexical_cast<string, double>);
