Here's a reduced example without casts and dereferencing the null-pointer:

====================================
struct A
{
    int i;
};

int foo(A *p)
{
    return &p->i - &(p->*&A::i);
}
====================================

This valid code snippet is rejected on the 3.3 branch.
It causes an ICE in fold_convert on the 3.4 branch.
