So far so good.

Boom! You've just caused a SIGSEV because you're assigning memory
that you haven't allocated properly. b1.u could point anywhere.
malloc and family are your friends.

Nope, that dog won't hunt. everything after your first invalid memory
reference creates undefined, probably fatal, behavior.
