Extremely high memory usage in linking of cubix package with optimisation
Because of performance problems in GHC, the full Cubix will not build with -O1 or -O2. We've tried on a server with 64GB RAM; the server ran out of memory.
Last month, we did manage to compile with -O2 successfully: on a server with over 200GB of RAM.
So clearly something is going very badly awry. They suggest that things explode during linking. However, I rather suspect that things first go off the rails during simplification.
