           Summary: no crash on use of a noreturn enum member
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW

For the following code there's no runtime crash

```
enum E {e1 = 1, e2 = 2, illegal = noreturn}

void main()
{
    E e;
    // that assignment should have the same effect as assert(0)
    e = E.illegal;
    // just to be sure
    if (e) {}
}
```
