  // We need to avoid having static constructors. This is accomplished by defining
  // a static array of the appropriate size and alignment, and defining a const
  // reference that points to the buffer. During initialization, the object will
  // be constructed with placement new into the buffer. This works with MSVC, GCC,
  // and Clang without producing dynamic initialization code even at -O0. The only
  // downside is that all external translation units will have to emit one more
  // load, while a real global could be referenced directly by absolute or
  // relative addressing.
  
  // Use an array of pointers instead of an array of char in case there is some
  // alignment issue.
