Avoid undefined-behavior
...
If a struct had (because it's a union) sizeof that is larger than the null_size,
we were providing only null_size bytes for its Null object. We know we'd never
access beyond that, but is undefined-behavior nonetheless according to the
standard.
The alternative fix would have required use of flexible-arrays, which are not
standard and have their own issues in various compiler. We've discussed that
extensively in the follow Mozilla issue (currently locked; I've asked that it
be opened):
