Progress, compiling with `dmd -g -m64 app.d && ./app.exe` (basically adding
-g), now works and get rid of the segfault:


```
import core.stdc.stdio;

enum Test {A, B, C}

Test test = Test.A;

extern(C) void main()
{
    switch(test)
    {
        default:
        break;
    }

    printf("the end");
}
```

So there is a problem somewhere with DMD not doing something important..
