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?

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.

as you can see debug with race must has "-N -l" setting, you even can not remove it

@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.

Alrighty, this is affecting quite a few people. Unassigning so it goes back in the triage queue.

mknyszek commented Nov 15, 2022

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).

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?

Code is https://github.com/abiosoft/colima, thanks for listening!

But where is it getting the code for, e.g., gvisor.dev/gvisor/pkg/refs.(*AtomicRefCount).DecRefWithDestructor?

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

@zwjzxh520 Can you try 1.20rc3? This issue should be fixed there.

Leaving this here in case it helps someone:

  1. Vendor dependencies
$ go mod vendor
  1. In vendor/gvisor.dev/gvisor/pkg/refs/refcounter.go, delete the line with the //go:nosplit directive

The 1.20 release fixes this for me.
