 Test program again

 {{{#!c++

 #include <boost/regex.hpp>
 #include <iostream>
 #include <exception>

 using namespace std;

 int main(int argc, char **argv) {

     try {
         boost::regex::flag_type flags = boost::regex::ECMAScript;
         flags |= boost::regex::nosubs;
         boost::regex theRegex("([|&])\\1?", flags);
         cout << "ok\n";
         return 0;
     } catch (exception &e) {
         cerr << "exception: " << e.what() << "\n";
         return 1;
     }
 }
