--- Comment #4 from Johannes Doerfert <doerf...@cs.uni-saarland.de> ---
Fixed in r252701. We now allow empty invariant equivalence class lists but do
not code generate them. I chose this fix because we cannot easily detect if we
have no users when we materialize a parameter and it is even harder to remove a
parameter that is already present in the SCoP. Lastly, it would have been
possible to change the isl_id payload for that parameter, though I think this
solution is nicer.
