runtime: hangs on windows with golang >= 1.14

[suikast42]

Does this issue reproduce with the latest release?

Yes.
Works with v <1.14. Last working version is 1.13.15

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

go env Output

What did you do?

create a simple hello world program
hello

• main
  • main.go

go run main.go runs every time as expected ( with go v 1.13.15)

But with go v > 1.14 it runs rarely. That means 99% of the cases it hangs.
After the hanging I can't interrupt the cmd window with Ctrl+C. So I must kill the cmd process. over the task manager.

I had an eye to the MCAfee Scanner. I let it deinstall from our IT-Department for testing. But the result was the same. Nothing changed.

Windows defender is disabled.

That's my output with the -x flag

go run -x main.go Output

C:\IDE\Projects_Git\playground\go\hello\main>go run -x main.go

WORK=C:\IDE\Programme\go\tmp\go-build432668794

After this output the run command hangs

What I have testet?

1. Deinstall MCAfee
2. Run command as Administrator
3. Set all path variables to C:\IDE... ( this area is not touched from MCAfee )
4. Testest not working versions 1.14 - 1.17

This could be an issue with async preemtion of goroutines added in go1.14. Try running your binaries with GODEBUG=asyncpreemptoff=1 set.

That's works as expected.

I found out that's works as well if I set GOMAXPROCS=1. What is the better workaround for that issue?

[D1CED]

Hi, I suggest you to keep this issue open for the Go team to see. Async preemtion not working properly is for sure a bug (in the runtime or OS or somewhere else) and people should not be expected to fall back to workarounds.

and people should not be expected to fall back to workarounds.

Agree. My bad ;-)

Maybe related to #36492.

@suikast42 Is it always hang or sometimes? Would it be possible for you to capture the program's state when it hangs?

Somtimes it works :-D

cc @aclements @alexbrainman

Sure. If you tell me how.

It could well be the same. #36492 is still broken for me as you can see from #36492 (comment).

Sure. If you tell me how.

@suikast42 what I do is I use Process Explorer program to see what happens to the Go programs (like go.exe and compile.exe and link.exe) that build my program. See #36492 (comment) for a screenshot of what I see. If you see some of Go build tools processes start and never exit, then you would have the same problem.

You can get Process Explorer from https://docs.microsoft.com/en-us/sysinternals/downloads/process-explorer

Here is a dump from Process Explorer. I hope that is what you mean.

@suikast42 I did not expect you to collect Process Explorer process dump. I will let @cherrymui reply what he expected you to collect.

Thank you.

Any fix for this issue in go 1.19 or later versions. We are also experiencing the same hang issue once we migrated to 1.17. Earlier we were using go 1.13.9 and we didn't had this issue.
