--- Comment #1 from Walter Bright <bugzilla@digitalmars.com> ---
The following:

```
union U {
    struct S {
        int a,b;
    }
    S data;
    int type:8;
}
pragma(msg, U.S.sizeof);
pragma(msg, U.sizeof);
```

prints:

8LU
4LU

Which is, of course, wrong. Curiously, if `int a,b;` is replaced with `long x;`, it prints:

8LU
8LU

Not specific to C, it equally affects D.
