laboger · 2017-12-19T14:07:27Z

What version of Go are you using (`go version`)?

go version devel +fdecaa8 Fri Dec 15 17:59:32 2017 +0000 linux/ppc64le

Does this issue reproduce with the latest release?

yes with latest upstream

What operating system and processor architecture are you using (`go env`)?

linux ppc64le, amd64

What did you do?

We have continuous builds of Kubernetes on upstream golang on ppc64le.

What did you expect to see?

successful builds

What did you see instead?

build failures (ICE) starting with commit fdecaa8

As noted above, we found this on ppc64le but it does also get an ICE on linux/amd64.

mvdan · 2017-12-19T14:48:17Z

@laboger could you please make sure it's still broken with the latest master? Asking because a similar regression was fixed recently in #23046.

mkumatag · 2017-12-19T15:04:22Z

@mvdan yes it is reproduced with latest golang master

laboger · 2017-12-19T15:30:34Z

Yes, it failed with latest upstream right before I opened this issue.

@laboger , I redid the kubernetes build according to your instructions (using tip with the fix) and I don't see any build errors. Are you still seeing this new problem?

mkumatag · 2017-12-20T13:14:31Z

@thanm this error is happening only on the ppc64le arch.

thanm · 2017-12-20T13:23:08Z

Thanks for the clarification. That is somewhat surprising given that the inliner is (more or less) target-independent, but I'll see what I can do about reproducing it.

laboger · 2017-12-20T13:38:36Z

If I can help narrow it down let me know what I can do.

thanm · 2017-12-20T14:44:20Z

OK, I finally have a handle on it now. Working on a fix.

Your latest CL allows the Kubernetes build to finish without error. Thanks.

thanm · 2017-12-20T16:43:05Z

Good to hear. Thanks for doing the additional testing.
