        <pre>John McCall asked me to file the following code reduction. Top-of-tree
generates a -Wglobal-constructors warning with the following code, but no
actual constructor is emitted.

struct Once {
  unsigned value;
  constexpr Once() : value(0) {}
};

template<typename T>
class Lazy {
  T t;
  Once once;
public:
  constexpr Lazy() = default;
};

Lazy<unsigned> lazy;</pre>
