go: runtime: "fatal: morestack on g0" on amd64 after upgrade to Go 1.21
Does this issue reproduce with the latest release?
Yes.
What did you do?
https://github.com/VirrageS/fluent-bit-go-bug here is full code to repo. I will try to make it smaller but for now this is all I have.
When running this project with:
docker build --build-arg="GO_VERSION=1.20" -t fluentbit .
docker run -t fluentbit
it runs correctly.
But when I change to GO_VERSION=1.21 it fails with fatal: morestack on g0:
docker build --build-arg="GO_VERSION=1.21" -t fluentbit .
docker run -t fluentbit
It looks like regression in Go 1.21. I found similar issues but those seem to be quite old and are not tied to Go 1.21 version.
I have tried to strace the binary and this is what I got:

@gopherbot please backport to 1.21. This is a fatal crash with no workaround for applications using C coroutine libraries and calling into Go. The fix here is fairly complex, so this is a medium+ risk backport, but we don’t have a simpler workaround to backport. That said, the fix has baked in post-submit for 2+ weeks without further issue.
@VirrageS could you verify that your application works properly with https://go.dev/cl/525455?
