        <pre>In c++98 sizeof on a non-static struct member was not legal without an
instance. c++11 allow it.
It's working fine with struct but not with nested struct.

Here an example to trigger the problem:

#include <iostream>

struct Foo 
{
    int m_member;

    struct Nested 
    {
        int m_nestedMember;
    };

    Foo()
    {
        std::cout << sizeof(Foo::m_member);          // Ok
        std::cout << sizeof(Nested::m_nestedMember); // Bug in clang in c++11
mode: error: invalid use of non-static data member 'm_nestedMember'
    }
};

int main()
{
    Foo foo;

    return 0;
}</pre>
