Bug ID: 124244
Summary: [reflection] maybe bogus -Wtautological-compare
warning
Product: gcc
Version: 16.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org

```
#include <meta>
static constexpr std::pair<int, short> p = {1, 2};
static_assert (&[:std::meta::reflect_object (p.first):] == &p.first);
```
compiles fine, but we emit:
w.C:3:57: warning: self-comparison always evaluates to true
[-Wtautological-compare]
3 | static_assert (&[:std::meta::reflect_object (p.first):] == &p.first);
| ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^~ ~~~~~~~~
Sure, let's warn for "&p.first == &p.first", but the warning above looks
questionable.
