<pre>The following code snippet does not compile using clang but according to the
standard it is valid:
class A {
protected:
struct B { };
};
struct D: A::B, A { };
clang fails with "error: 'B' is a protected member of 'A'"
According to the current standard
(<a href="http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3337.pdf">http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2012/n3337.pdf</a>), this is
valid because
"the use of A::B as a base-specifier is well-formed because D is derived from
A, so checking of base-specifiers must be deferred until the entire
base-specifier-list has been seen."</pre>
