Relevant Godbolt: https://godbolt.org/z/9cqnvTG3q
The following snippet fails to compile:
```c++
//namespace Bar { // fixes everything
struct Bar {
enum Foo {
A = 1,
B = 2,
C = 4
};
};
using B = Bar;
int main() {
using enum B::Foo;
// Using individual `using`
// statements per-constant
// doesn't make any difference,
// except when lowering from
// -std=c++20 to -std=c++17, which
// compiles fine.
//using B::Foo::A;
//using B::Foo::B;
int f = (A|B); // segfault
//int f = (A); // weird error
//int f = A|B; // OK
}
```
Uncommenting the various marked lines will demonstrate a few different strange failure cases.
