Unit tests on linux have OOMed - probably memory leak or faulty shrinker.

Is there an upstream ticket about this?

Interestingly, with this combination of commits you can't seem to build the ledger-spec tests:

[ 9 of 20] Compiling Test.Shelley.Spec.Ledger.ConcreteCryptoTypes ( src/Test/Shelley/Spec/Ledger/ConcreteCryptoTypes.hs, /home/jule/git/iohk/cardano-wallet/dist-newstyle/build/x86_64-linux/ghc-8.6.5/shelley-spec-ledger-test-0.1.0.0/build/Test/Shelley/Spec/Ledger/ConcreteCryptoTypes.o )

    Module ‘Cardano.Crypto.Hash’ does not export ‘MD5Prefix’

Via e.g. cabal build --enable-tests all.

@hasufell Yes, it needs a newer revision of cardano-base. The error was in cardano-node/cabal.project, which is our reference.

I'm not sure why you are running the tests of all dependencies, but fwiw PR #2088 will fix it.

Building, not running. This is more of a cabal oddity when passed --enable-tests. I think this will be gone in cabal-3.4.0.0, which doesn't treat source-repository packages as local anymore.
