Won't compile with GHC >= 8.10 #2

Closed konn closed 4 years ago

Compiling with GHC 8.10, with nightly-2020-06-29 build-plan, mpi-hs fails to compile with the following error:

$ stack build mpi-hs --resolver nightly

It seems that GHC.Arr.indexError has gone in base >= 4.13.0.0.

Also (silently) reported here: https://github.com/commercialhaskell/stackage/issues/5444

Thanks for the notice. I uploaded a new version 0.7.2.0 that drops the dependency on GHC.Arr.indexError.
