Linux 2.4.17, glibc 2.2.2
>Description:
The operator>> on a string does not only read a single word, but the whole file. This is at least (I don't have the standard at hand) contrary to what Josuttis writes in his book and contrary to the other GCC versions I know (including 3.2).

-- stream.cpp ---
// If it worked correctly, only the // would appear!
#include <fstream>
#include <iostream>
#include <string>
using namespace std;
int main (int argc, char** argv) {
   ifstream is("stream.cpp"); // This file.
   string line;
   is >> line ;
   cout << line << endl;
}
