ghc-8.6.1 and ghc-8.6.2 use a lot of memory
Currently GHC uses a lot of memory to build a relatively small module and causes my CI to fail due to there being a 4G memory limit.
The source code can be found here:
https://github.com/haskell-works/hw-json/tree/73368cee21dc72eedd5291ba689f9abf10e7fcd2
The problem module is here:
The build output follows:
cabal new-build --enable-tests --enable-benchmarks --project-file="cabal.project" -j${CABAL_THREADS:-4} all
Build profile: -w ghc-8.6.2 -O2
In order, the following will be built (use -v for more details):
- hw-json-0.9.0.1 (lib) (first run)
- hw-json-0.9.0.1 (test:hw-json-test) (first run)
- hw-json-0.9.0.1 (exe:hw-json) (first run)
- hw-json-0.9.0.1 (bench:bench) (first run)

cabal: Failed to build test:hw-json-test from hw-json-0.9.0.1. The build
process was killed (i.e. SIGKILL). The typical reason for this is that there
is not enough memory available (e.g. the OS killed a process using lots of
memory).
