Not false: It is extra fields and extra lines of code. The fact that
it is well defined doesn't make it any less bogus. But again, that's
just opinion, much like your objection to the equally well defined
structure it replaces is bogus.

Your solution doesn't solve the sizeof issue. Don't pretend it does.
Both ways allocate a random amount of memory larger than sizeof the
structure.
