Reduced testcase:
```
struct a
{
  static constexpr int value = 1;
};

int main() {
    [](auto level1) {
        return [&](auto ) {
            return [&](auto level3) {
                if constexpr (decltype(level3)::value) {
                    static_assert(decltype(level1)::value, "");
                }
                return 0;
            }(a{});
        }(0);
    }(a{});
}
```
