Hmm... that's an sbrk panic [1], indicating that setheap hadn't been
called. zfsgptboot is zfsboot with gpt bits included, so the relevant
setheap call is [2] I believe. It's not immediately clear to me how
switching interpreters could actually be breaking it in this way.

At what point are you hitting this panic? After menu, before kernel transition?
