>Description:

If you compile the code below the first error in function f() correctly
issues a diagnostic about invalid use of a non-static data member, but the
second function, B::f() causes an ICE. The only difference is that one
function is a class member.

>How-To-Repeat:

struct A
{
    char a;
};

struct B
{
    void f(const A&) const;
};

void f(const A& a)
{
    unsigned s = sizeof(A::a);  // ERROR -> diagnostic
}

void B::f(const A& a) const
{
    unsigned s = sizeof(A::a);  // ERROR -> ICE
}


>Fix:
	Don't write bad code.
