--- Comment #5 from Ilia Taraban <ilia.tara...@intel.com> ---
After your commit now I have assert in FE on similar test:

=============== fine.cpp ==============

struct A {
        void foo(int) __unaligned {;}
};

void func(void (A::*a)(int) __unaligned); 


void goo() {
  func(&A::foo);
}

=======================================
