[Bug middle-end/32492] [4.3 Regression] attribute always_inline -> sorry, unimplemented: recursive inlining

I've reproduced the same problem with official GCC 4.3.1 on Linux amd64.

template<typename T>
struct B {
        struct C {
                __attribute__((always_inline)) C(C const &c)
                {
                }
        };
        void __attribute__((always_inline)) g(C c)
        {
        }
};

void trigger(B<int> b, B<int>::C c)
{
        b.g(c);
}
