Describe the bug
First of all: Thank you for the amazing work you did here.
Consider this minimal example code:
#include <experimental/meta>
#include <vector>
namespace __impl {
template<auto... vals>
struct replicator_type {
template<typename F>
constexpr void operator>>(F body) const {
(body.template operator()<vals>(), ...);
}
};
template<auto... vals>
replicator_type<vals...> replicator = {};
}
template<typename R>
consteval auto expand(R range) {
std::vector<std::meta::info> args;
for (auto r : range) {
args.push_back(std::meta::reflect_result(r));
}
return std::meta::substitute(^__impl::replicator, args);
}
class simple_test_class {
public:
int a;
void f() {
}
};
template<typename T>
constexpr void create_function_member_information() {
std::vector<int> result;
[:expand(std::meta::members_of(^T)):] >> [&]<auto e> {
};
}
int main() {
create_function_member_information<simple_test_class>();
return 0;
}
Compiling this with the latest checkout of this compiler results in a crash:

The interesting part is: If I change the std::meta::members_of to std::meta::nonstatic_data_members_of the compiles and works as expected. So it seems closely related to the std::meta::members_of implementation.
Environment (please complete the following information):
- I tested this on two different systems both on Windows using a WSL environment with Ubuntu 22.04
Additional context
If you need any other debug information I will do my best to provide it

Thanks for the bug report! This is now fixed at HEAD, and should be fixed on Godbolt the day after tomorrow.
