          Issue ID: 24701
           Summary: No error produced from casted noreturn variable
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody@puremagic.com
          Reporter: elpenguino+D@gmail.com

```
void main() {
    noreturn foo;
    try {
        //auto a = cast(int)noreturn.init; // error properly produced
        auto a = cast(int)foo;
        assert(0);
    } catch (Throwable e) {
        assert(e.msg == "Accessed expression of type `noreturn`");
    }
}
```

In this example, cast(int)foo results in an int(0). An error is expected, as in
cast(int)noreturn.init.
