[boost] sregex_token_iterator bug?

20 Mar 2004

      gcc 3.3.3 with boost 1.31.0 on GNU/Linux:

...
cat moo.cc
#include <iostream>
#include <string>
#include <boost/regex.hpp>
using namespace std;
using namespace boost;
int main() {
    string s;
    getline(cin, s);
    sregex_token_iterator i(s.begin(), s.end(), regex("\\s+"), -1);

    cout << "x" << *i << "x" << endl;
    ++i;
    cout << "x" << *i << "x" << endl;
    ++i;
    cout << "x" << *i << "x" << endl;
}

g++ -Wall -W moo.cc -o moo -lboost_regex

Segmentation fault

However, the first example given in
http://boost.org/libs/regex/doc/regex_token_iterator.html works fine, so I
don't know what's going on.
