Never safe, because base contains the runtime and the runtime and the compiler are very tightly tied together. Crashes are not surprising.

Actually it should always be safe: --allow-newer=base is essentially the equivalent of removing the upper bound on base from the .cabal file (of every package that was installed during that run).

However, I'm quite confused about something, namely that as far as I can tell, neither accelerate nor any of its dependencies contain a module Data.Label.Base. What package was GHC trying to build when it crashed?
