... that the implicitly instantiated copy constructor (as well as assignment
operator, for that matter) will copy this->typed as a char[]/uint64_t union,
while it actually contains a value of type Register. You need an explicit copy
constructor that would assign this->typed with the correct type via
'typed.addr() = ...' like the existing constructor does.
(If T was POD, you could have had it in the union in the first place, and this
issue wouldn't arise)
