Re: bug in libstdc++ bitset

[Andrew Pinski <pinskia at physics dot uc dot edu>]

After changing it to let it compile under 3.x,
#include <bitset>
#include <iostream>
using namespace std;

int main() {
        bitset <33> b;
        b.set(32);
        cout << b << ' ' << b.count() << ' ' << b.none() << '\n';
}

With the current cvs, it compiles fine and outputs:
100000000000000000000000000000000 1 0

which looks to be the right answer.

Thanks,
Andrew Pinski
