Hi devs, Some GHCi tests (but far from all!) hang on my Mac. I can't reproduce this behavior outside the testsuite driver, so I think it's the Python code, not the Haskell. Failing tests: ghci/prog017/prog017 ghci/scripts/T6018ghcifail ghci/scripts/T6018ghcirnfail And that's it! My Python reports that it's 2.7.13. Any leads to follow? Thanks, Richard
