Bug ID: 87784
Summary: A bug in tr2::dynamic_bitset::find_first
Product: gcc
Version: 8.1.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: yusemru at gmail dot com

source code
Consider the following code:
#include <iostream>
#include <tr2/dynamic_bitset>
using namespace std;
using namespace tr2;
int main() {
dynamic_bitset<uint64_t> b;
b.push_back(0);
b.push_back(1);
dynamic_bitset<uint64_t> a;
a.push_back(0);
a.push_back(0);
cout << b.find_first() << ' ' << a.find_first() << endl;
return 0;
}
On my machine it prints 2 2, which is clearly wrong.
I'm using GCC 8.1.1 on Arch Linux x86-64
