Here's some code that has been compiling till at least 1.50, and starting long before. I isolated the part that breaks to create a program. Here it is: Just taking a std::vector of int and copying into strings. #include <boost/lexical_cast.hpp> #include <vector> #include <string> using namespace std; int main (int, char **) { vector<int> values; vector<string> ret; std::transform(values.begin(), values.end(), ret.begin(), boost::lexical_cast<std::string, int>); } And compiling on fedora 18, gcc 4.7 (Got same issues, I believe, with MSVC 10) I get the output at the bottom. Anyone has an idea on what the problem could be?
