Comment at: clang/test/Frontend/noderef.c:71
+ x = sizeof(s->a + (s->b)); // ok
+
// Nested struct access
----------------
Can you add tests for the weird situations where the expression actually is evaluated? e.g.,
```
struct S {
virtual ~S(); // Make S polymorphic
};
S NODEREF *s;
typeid(*s); // Actually evaluates *s at runtime
struct T {
unsigned i;
};
T t1;
T NODEREF *t2 = &t1;
sizeof(int[++t2->i]); // Actually evaluates t2->i at runtime
```
