Bug ID: 108214
Summary: writinng bitset to stringstream fails
Product: gcc
Version: 13.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: rhalbersma at gmail dot com
Target Milestone: ---
#include <bitset>
#include <sstream>
int main() {
using T = std::bitset<1>;
T a(1);
T b;
std::stringstream sstr;
sstr << a;
sstr >> b;
}
The above program works correctly for g++ until version 12, but for version 13
(trunk) it errors out with: "terminate called after throwing an instance of
'std::invalid_argument' what(): bitset::_M_copy_from_ptr"
