What did you do?

I compiled a Go source code with go1.17rc1!

What did you expect to see?

I expected the resulted binary to run successfully just like when compiled with go1.16.5

What did you see instead?

running the binary:

Thanks for reporting, @urbanishimwe .

Could you please include instructions for reproducing the problem, e.g. what application you built and how you ran it when you encountered this crash? Thanks.

[cherrymui]

@urbanishimwe is your code using the golang.org/x/sys repo? If so, could you try updating that repo? (See #46645) Thanks.

[urbanishimwe]

@cherrymui it seems to update golang.org/x/sys(v0.0.0-20201101102859-da207088b7d1 => v0.0.0-20210630005230-0f9fa26af87c) fixes the issue!

[cherrymui]

Thanks for confirming.

$go version
go version go1.17 darwin/amd64

I'm using go1.17 from https://golang.org/doc/install and encountering the exact same problem when running a test.

@MuyaoXiao try go get -u golang.org/x/sys

[mooxiu]

go get -u golang.org/x/sys

Thank you! I missed out the comment above, silly me!
