This may have the same root cause as #45700, but the fact that it only occurs on the 10_12 builder (and occurs consistently there) is a bit strange.

Marking as release-blocker for 1.17 via #11811.

cagedmantis · 2021-04-23T15:08:08Z

I wanted to note that macOS 10.12 will not be supported in Go 1.17. The macOS 10.12 post-submit builders no longer run for commits made on master.

bcmills · 2021-04-23T18:49:04Z

In that case, this issue can probably be closed.

Is there a tracking issue for dropping macOS 10.12 support? (I don't currently see a release note for it.)

mark-rushakoff · 2021-04-28T16:38:02Z

I believe I'm running into this bug, but on macOS 10.14 -- I have spent a fair bit of time trying to minimize the reproducer and unfortunately I don't have something I can share externally yet.

I can reliably reproduce it in a closed source project. This project does use cgo to link against some libraries built in rust, but it successfully builds and runs with go1.15. The resulting output looks like this at tip (go version devel go1.17-5b328c4a2f Wed Apr 28 16:13:40 2021 +0000 darwin/amd64):

And I tried to git bisect on go, and unfortunately I landed on fd3612e, internal/buildcfg: enable regabiwrappers by default.

If this should be a different issue, I'm happy to open a new one. I'm also happy to try bisecting again if you can point me at the right flags to pass before regabiwrappers were on by default, or I can easily build go if there are experimental patches to try or anything to gather more output.

I poked at it just a bit longer and was able to minimize a reproducer at https://github.com/mark-rushakoff/goissue45702.

Change https://golang.org/cl/316649 mentions this issue: internal/syscall/unix: use internal/abi.FuncPC for syscall wrapper

cherrymui · 2021-05-03T22:22:50Z

@mark-rushakoff thanks for reporting. If you could try applying change https://go-review.googlesource.com/c/go/+/316649 to Go tip and run your test case, that would be very helpful. Thanks.

Following CL 313230, this is for internal/syscall/unix package. Updates #45702.

@cherrymui Is this resolved? If so, please feel free to close at your leisure.

Not yet. I'll send another CL later today. Thanks.

Change https://golang.org/cl/317894 mentions this issue: unix: take address in assembly for Darwin syscall wrappers

In Go 1.17 we will introduce a register-based ABI on some platforms, as well as ABI wrappers to bridge the ABIs. For Darwin syscall wrappers, it needs to be called directly, instead of through wrappers. Currently, it is written as that the syscall functions are defined in assembly and their addresses are taken from Go using funcPC. In Go 1.17 this will result in the address of the ABI wrapper, which is undesired. In the syscall package in the standard library we changed to use a compiler intrinsic internal/abi.FuncPCABI0 to take the address of the syscall function. But that is not available to this repo and not available in older versions of Go. Here we take a different approach: taking the address directly from assembly. This also ensures we get the address of the defined syscall function, not the ABI wrapper. Updates golang/go#45702.

@mark-rushakoff does it work now with an updated x/sys repo? Thanks.

mark-rushakoff · 2021-05-07T18:12:51Z

@cherrymui I have tried doing a go get golang.org/x/sys@master && go mod vendor from both the src/ and the src/cmd directories, but my tests are still failing with what looks like the same stack. I suspect I'm not correctly updating x/sys -- I couldn't quickly find the right way to do that. Can you point me in the right direction?

cherrymui · 2021-05-07T18:20:16Z

from both the src/ and the src/cmd directories

Do you mean GOROOT/src and GOROOT/src/cmd? I think you may want to update golang.org/x/sys in your repo, not the one that are vendored into GOROOT.

cherrymui · 2021-05-07T18:23:56Z

Also, when you paste the stack trace, could you paste the part that is after the hex dump? That will provide more useful information, such as the source code path of the x/sys code.

mark-rushakoff · 2021-05-07T18:45:34Z

@cherrymui yes, I was mistakenly attempting to update x/sys in GOROOT.

After running go get golang.org/x/sys@master, I am able to successfully run my tests without any unexpected return pc errors, using go version devel go1.17-af6123a865 Fri May 7 18:14:25 2021 +0000 darwin/amd64.

Thanks again!

cherrymui · 2021-05-07T20:02:41Z

Thanks @mark-rushakoff !

I think we can call this issue fixed. macOS 10.12 is no longer supported. And other failures reported in the issue are fixed.
