Bug ID: 126036
Summary: [reflection] ICE on assignment members_of into
constexpr variable
Product: gcc
Version: 17.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: kengusername at proton dot me
Target Milestone: ---
This program fails to compile on gcc 17 trunk
https://godbolt.org/z/8eqGcsaET
```
#include <meta>
namespace details {
int a;
};
template<auto = 0> consteval auto gen() {
constexpr auto range = std::meta::members_of(^^details,
std::meta::access_context::unchecked());
}
```
this example also triggers an ICE:
https://godbolt.org/z/vGYdKnETx
```
#include <meta>
enum xyz {a};
template<auto = 0> consteval auto gen() {
constexpr auto range = std::meta::enumerators_of(^^xyz);
}
```
However it fails properly without templates:
https://godbolt.org/z/4zrhxbGTb
```
#include <meta>
namespace details {
int a;
};
consteval auto gen() {
constexpr auto range = std::meta::members_of(^^details,
std::meta::access_context::unchecked());
}
```
This suggests that this is an issue with the way metafunctions return vectors.
All of these examples behave the same way on gcc 16.1 with assertions.
