Bug ID: 101571
Summary: DestroyGuard used by the ranges::uninitialized family
should use addressof()
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: hewillk at gmail dot com
Target Milestone: ---
The Standard Library should consistently use addressof() to defend itself
against overloaded operator&().
#include <memory>
struct I {
using value_type = std::string;
using difference_type = std::ptrdiff_t;
I& operator++();
I operator++(int);
value_type& operator*() const;
void operator&() = delete;
bool operator==(const I&) const;
};
int main() {
std::ranges::uninitialized_default_construct(I{}, I{});
}
