Hi there, I am in the process of porting Beats on s390x architecture and noticed that there are multiple segmentation violation when running test cases (Most of the beats - for example Filebeat, Packetbeat, Heartbeat has this error). This also happens on x86 arch (Linux 2a4cae7a4792 4.15.0-29-generic #31-Ubuntu SMP Tue Jul 17 15:39:52 UTC 2018 x86\_64 x86\_64 x86\_64 GNU/Linux) /============================================/ ...

Hmmm, this is a bit odd, we do run our internal builds on 1.13.6, and they do pass consistently on linux. Out of curiosity, what happens with 1.13.6 when running `mage goTestUnit`? ---

Something weird is going on here, the tests for the beats codebase are run daily on my (linux x86\_64) laptop, our CI servers, and tons of developers and others. I never hear about segfaults as an issue. I suspect there's something about your environment that's off but it's really hard to say what it is. Have you tried building it in an other environment? ---

Yes - I tried in couple of envt with similar results. Wonder if it is related to : [https://github.com/elastic/beats/issues/13910](https://github.com/elastic/beats/issues/13910)? ---

Which branch are you on? Have you tried this on master? There may be some issues with your setup on 7.5 I hear. ---

And to confirm, this is all on x86\_64 _and_ s390x where these issues are occurring right? ---

I have been using 7.5.1 branch where this problem occurs. Master works just fine with Go 1.13.6 In the link I mentioned above there are some workarounds mentioned which fixes the issue (adding `testing.Init()` in the code which has made its way to the master branch). Wonder if 7.5.1 docs can be changed to reflect this behavior - i.e., use Go 1.12.9 with 7.5.1? ---
