Description

I am seeing T3171 fail with incorrect stderr output on Darwin (e.g. ​https://circleci.com/gh/ghc/ghc/7106): 

Actual stdout output differs from expected:
--- ./ghci/should_run/T3171.run/T3171.stdout.normalised	2018-07-14 21:24:25.000000000 -0700
+++ ./ghci/should_run/T3171.run/T3171.run.stdout.normalised	2018-07-14 21:24:25.000000000 -0700
@@ -1 +0,0 @@
-Interrupted.

Architecture: Unknown/Multiple → x86_64 (amd64)
Operating System: Unknown/Multiple → MacOS X

Unfortunately it looks like this test is just fragile on Darwin; the same commit failed once but passed in another CircleCI build.

It turns out that this also fails on Linux/i386.

Milestone: 8.6.1 → 8.8.1

These won't be fixed for in GHC 8.6.

It fails every now and then (not always!) on i386 linux indeed: ​https://circleci.com/gh/ghc/ghc-diffs/269

In 3040444/ghc: 

tests: increase (compile) timeout multiplier for T13701 and MultiLayerModules

Summary:
Those tests are currently making our i386 validation fail on CircleCI:

Test Plan: Using my Phab<->CircleCI bridge to run i386 validation for this diff.

Indeed this also appears to happen (​occasionally) on Fedora/amd64.

Operating System: MacOS X → Unknown/Multiple
Priority: normal → high

I'm disabling this test for now until we can investigate. Raising priority so this happens.

In 817ba0c/ghc: 

testsuite: Skip T3171 for now

This test is remarkably flaky, failing regularly on i386/Linux,
amd64/Fedora, and amd64/Darwin. I've opened #15383 to track this and am
disabling the test for now until we have a chance to investigate.
