Comment:

 Currently my last known good commit is commit:d78dde9.

 At changeset:bdfc85b I see the following tests failures during validate:

 SUMMARY for test run started at Wed Jul 18 12:35:24 2018 CEST
  1:18:37 spent to go through
     6386 total tests, which gave rise to
    19686 test cases, of which
    13227 were skipped

       38 had missing libraries
     6190 expected passes
      176 expected failures

        2 caused framework failures
        1 caused framework warnings
 }}}

 Note the large number of GHCi tests failing.

 I will now bisect in that range above.
