          Issue ID: 23336
           Summary: cannot take const struct member address at CTFE
           Product: D
           Version: D2
          Hardware: All
                OS: All

It's possible to take the address of a global struct variable and store it in a
const variable, but you can't take the address of a struct member:
```
struct S
{
    uint a, b;
}
__gshared const S d = {3, 4};

__gshared const e0 = &d; // allowed
__gshared const e1 = &d.a; // error
```

The error is: cannot use non-constant CTFE pointer in an initializer `&d.a`
