Preprocessed source is as you might expect, given the lack of includes:
struct A {};

template<int> void foo(void (A::* f)())
{
  A a;
  &(a.*f);
}

template<int> void bar(void (A::* f)())
{
  A *p;
  &(p->*f);
}

Ah, Andrew, before you beat me to it...  this doesn't ICE if you pass
-fno-ms-extensions, and it does ICE on Linux if you pass -fms-extensions
