Non-deterministic segmentation fault in cryptohash-sha256 testsuite

$ cabal get cryptohash-sha256-0.11.101.0
$ cd cryptohash-sha256-0.11.101.0
$ cabal new-run -w ghc-8.6.1 --enable-test --allow-newer="*:base,*:stm,*:tasty" test:test-sha256 -- -j 8 --quickcheck-tests 9999

Eventually the program will start spamming stderr with test-sha256: lost signal due to full pipe: 11 repeatedly. This apparently only started with 8.6.1.
