IMO the main bug here is that functions.c isn't expecting qd->dest to be
overwritten, so we could work around it by keeping a separate private
copy of the dest pointer. However, it would also be fair to ask whether
there's not a cleaner solution. Perhaps the intoRel stuff should be
saving/restoring the original destreceiver instead of just blindly
overwriting it.
