c) Throw an error. More than likely this will indicate a coding problem, and
just passing a copy will cause a developer to scratch her head and say
"WTF?" for several months while trying to figure out the problem(s). Leaving
behavior as undefined will just cause memory corruption problems for sloppy
developers, which is what we want to get away from in the first place.
