Returning a function pointer from a constexpr function is leading to an error,
in a context where using the function pointer directly does in fact work. I
don't see why it should be different.
I already asked the isocpp group about this:

They stated: "This is a GCC bug. Pointers to functions with internal linkage
are fine since C++11."
