The TestLoadImportsGraph test is failing on s390x on latest x/tools commit (golang/tools@51295c7). It can be seen at

It happens with Go on latest tip (44cf595), as well as with latest release-branch.go.1.11 (e39e43d).

There's a very good chance this is the same issue as #29445 (/cc @mvdan), but this issue is specifically about the s390x failure, which we need to fix for #11811.

I'll wait to see if @mvdan's CL fixes this once it's submitted. If not, we'll have to debug it on a s390x machine. (I might get to "hack into a mainframe"!)

CL 156977 has fixed the issue for s390x as well. It must've been using a custom GOCACHE all along, before all the other environments started to as well.

Thank you @mvdan and @matloob!
