I've created an MR to hopefully resolve this issue (https://gitlab.haskell.org/ghc/ghc/merge_requests/400). If you are eager to make use of this, and/or confirm that it solves the issue, you can e.g. cherry pick the commit:

$ git remote add DavidEichmann https://gitlab.haskell.org/DavidEichmann/ghc.git

$ git fetch DavidEichmann

$ git cherry-pick davide/TestRunnerCrash-NonGitRepo
