If I understand correctly, each `authzPB` collected in the iteration stores references to fields of an `authzModel`. Before the patch, these were identical, referring to the fields of the loop variable v. Each iteration of the loop, v is set, and all those stored references pointed to the new value. Rust does give a compilation error for that.
