Change https://go.dev/cl/421954 mentions this issue: syscall: fix sycall.ptrace cause nosplit stack over 792 byte limit
Why is this case important? The only reason to use -all=N -l is for debugging. Why is it necessary to debug code compiled with -race?
Why is this case important? The only reason to use
-all=N -lis for debugging. Why is it necessary to debug code compiled with-race? the -"all=-N -l" is added by Goland 's debugger auto, some time may need to debug with race like some go test -v -race report a issue. I will do this sometimes.
@ghostiam please tell us your scene!
package main
import (
"os/exec"
"testing"
)
func TestA(t *testing.T) {
cmd := exec.Command("echo", "test")
_ = cmd.Start()
}
below is Goland debug setting
as you can see debug with race must has "-N -l" setting, you even can not remove it
click with debug
@ianlancetaylor
debug with race to fix sync issues is quite usually for Gland users like me!
@ghostiam please tell us your scene!
I also have "-race" added to all projects that I develop by default so that I can always get race information. I don't feel comfortable removing "-race" when I need to debug. Everything worked correctly before, why shouldn't it work now?
I'm not certain what we're going to do about this as this isn't necessarily a supported build configuration (AFAICT).
@cuonglm filed an upstream bug with Goland: https://youtrack.jetbrains.com/issue/GO-13486/Show-warning-when-debug-is-started-with-the-race-option. Assigning this @cuonglm for now. (Feel free to unassign! This is non-binding, just for triage. :))
@mknyszek in VSCode (with vscode-golang), the settings used when running/building tests are the same for running tests and debugging tests, and there is no easy way to pass settings just for debugging or just for testing. This problem affects my company because we want to always enable the race detector when running tests, so we ship a shared config that sets
"go.testFlags": ["-race"]
Unfortunately, this bug means that when we upgraded to 1.19, we can no longer use the debugger in vscode through vscode-golang, since it automatically includes the test flags when building the debug binary. This works just fine in 1.18, but breaks in 1.19, so we've since downgraded to 1.18.
I don't know the best way to fix this; it's possible that in vscode-go (and i guess in other editors like Goland, as reported above) it could be solved by making it possible to pass flags "just when running tests" and "just when debugging tests". But that means every editor / setup needs to support that, and in general, encouraging your debug/testing/building code to special-case certain paths leads to increased chance of divergence and unexpected problems.
I think that this should be considered a supported build configuration because ~i'm using it~ it's likely that many VSCode users would like to use the race detector by default, and also want to be able to debug their tests. I cannot prove this though!
I'm still having this issue on go version go1.19.3 darwin/arm64 even without -race enabled. I'm getting this error because of an upstream dependency on gvisor. Running go build with flags -gcflags all=-N -l.
gvisor.dev/gvisor/pkg/refs.(*AtomicRefCount).DecRef: nosplit stack over 792 byte limit
Alrighty, this is affecting quite a few people. Unassigning so it goes back in the triage queue.
To be clear, I'm not saying that we're necessarily going to make this a supported build configuration, but we should figure out what we're going to do.
@clarkmcc Unfortunately, that case seems gVisor-specific. They use //go:nosplit directly which is not backed by the Go 1 backwards compatibility guarantee outside the standard library (https://groups.google.com/g/golang-nuts/c/Tq3cFNlg7ac/m/okpXURdiAgAJ). (We wouldn't pull the rug out from everyone using //go:nosplit without a warning, but it is technically an implementation detail and the Go runtime's implementation may change.) I think it's up to them if they support the -gcflags all=-N -l configuration.
This is different from OP's error because that's a break in standard library usage (for a technically unsupported configuration, but one that is apparently difficult for many to work around at this point in time).
There's discussion in #51256 that's relevant to fixing these nosplit stack overflow issues at a deeper level, though we probably want a shorter-term fix for this.
The discussed fix on our side is to increase the stack guard for -race builds. We might be able to do this in objabi.stackGuardMultiplier, since -race applies to the whole build anyway (stackGuardMultiplier can go sideways can be different for different packages in a build).
Change https://go.dev/cl/451217 mentions this issue: runtime,cmd/link: increase stack guard space when building with -race
Is there an interim workaround for this problem in GoLand on mac M1? I'm unable to debug one project... (I also see this using go version go1.20rc1 darwin/arm64)
@rfay This should be fixed in go1.20rc1. If it isn't, please provide a stack trace or reproduction details so we can take a look.

That looks like there are nosplit directives in user code, which isn't supported. Specifically, in gvisor.dev/gvisor/pkg/refs.
But looking at https://pkg.go.dev/gvisor.dev/gvisor/pkg/refs, I don't see that code, or even those types. Where does that code come from?
But where is it getting the code for, e.g., gvisor.dev/gvisor/pkg/refs.(*AtomicRefCount).DecRefWithDestructor?
- gvisor uses a phantom setup for
go get, https://github.com/google/gvisor#using-go-get go get -u gvisor.dev/gvisor/runsc@goand thengo get -u ./... && go mod vendor
Seem to solve this, even for go 1.19.4

I was just trying to do a PR to colima :) I guess I'll do a first PR with a vendor upgrade.
Hi all, still having the same problem on my intel mac.
golang version is 1.19.5
Leaving this here in case it helps someone:
- Vendor dependencies
$ go mod vendor
- In
vendor/gvisor.dev/gvisor/pkg/refs/refcounter.go, delete the line with the//go:nosplitdirective
