I still cannot reproduce (on linux), and I don't get why you would expect a
runtime hook for a switch statement over an integer. If I adapt your example to
use final switch:

```
enum Test {A, B, C}

Test test = Test.A;

extern(C) void main()
{
    final switch(test)
    {
        case Test.A:
        case Test.B:
        case Test.C:
    }
}
```

I get:

test_.d(7): Error: `object.__switch_error` not found. The current runtime does
not support generating assert messages, or the runtime is corrupt.

Which looks like what you want.

Are you sure the segfault is because of the switch, or could it have to do with
thread local storage not being initialized on Windows without druntime?
