[Bug libstdc++/15361] New: bitset<>::_Find_next fails

["igodard at pacbell dot net" <gcc-bugzilla at gcc dot gnu dot org>]

The code:

#include    <bitset>
#include    <iostream>
using namespace std;

int main() {
    bitset<256> b;
    b.set(225);
    b.set(226);
    cout << b.count() << ":" << b._Find_first() << ":" << b._Find_next(225)
    << ":"  << b.test(225) << ":" << b.test(226) << ":" << b.test(227) << endl;
    return 0;
    }

produces:

~/ootbc/common/test/src$ a.out
2:225:256:1:1:0

That is, the bitset correctly has two members, and they are correctly 225 and 226, but _Find_next(225) returns end-of-set (256) rather than the next value (226)
