g++-2.95.4 writes 01.
The following program prints 00 instead of the expected 01 (not sure, but it
seems like a defect to me). Once you call s >> i, all further str() updates
are ignored by >>.
#include <sstream>
#include <iostream>
main() {
std::istringstream s("0");
int i;
s >> i;
std::cout << i;
s.str("1");
s >> i;
std::cout << i;
}

------- Additional Comments From pcarlini at suse dot de 2004-06-15 09:56 -------
Not a bug. At the end of the first call of operator>> the eofbit is set in s.
Then, at the beginning of the second operator>> the sentry finds eofbit set and
the whole input operation fails: i remains == 0. Just add s.clear(); in the
middle to get what you want.
