test case

const_union_member.cpp:5:3: error: constructor for 'Foo<int>' must explicitly
initialize the const member ''
  Foo()
  ^
const_union_member.cpp:21:12: note: in instantiation of member function
'Foo<int>::Foo' requested here
  Foo<int> baz;

Both gcc and msvc accepts the code, and no error is generated if const or
template is dropped.
