Yes, I agree, will file a bug this evening. On Wed, May 17, 2017 at 10:26 AM Ben Gamari wrote:

Hi Ben

I built from source and ran the tests on my Mac and found some problems. I'm not sure if the failing tests have been ran successfully by others on this platform. I did "make slowtest". Maybe the problem only happens on my machine.

Currently Harbormaster only runs `make test`, not `make slowtest`. Consequently, `slowtest` is generally rather broken, even on Linux. Every once in a while I look at it and try to pare down the failures, but it's an up-hill battle.

...

I'm new to running the testsuite and not sure how the sleep settings on my computer affect long running computations.

- If I want to run a long running test such as "make slowtest" overnight will my computer go to sleep preventing the test from running? i.e. should I invoke it with something like "caffeinate -i make slowtest" ?

That sounds right to me.

...

I almost didn't run the tests assuming they had been run as part of the release process but then I guessed that maybe slowtest had not been run. It would be a pain but would it be worth documenting which tests had been run on which platforms?

I currently don't validate the binary distribution tarballs. Instead I judge validation state from Harbormaster's testing of the ghc-8.2 branch.

Over the summer we intend on revamping our CI infrastructure, which should make it easier to do nightly runs of slowtest (and perhaps provide nightly or even per-commit binary distributions).

...

I assume I should file a bug for the following?

That would be great. I had a quick look at this and it looks quite likely that the simplifier is looping: even -fsimpl-tick-factor=1000 doesn't succeed. This looks like a real regression.

Cheers,
