--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
For more background, see:

The code is ill-formed because 'fooAddr' does not refer to a function or an
array (it refers to a pointer), and thus you cannot omit the '&'. (More
generally, the intent was that C++11 did not let you do new things here, such
as pushing the address through a constexpr variable.)
