What did you do?

our CI tests started to have this sporadic panic since we upgraded from Go 1.25.8 to Go 1.26.2
The panic occurs only on windows and during execution of tests, we didn't notice any failure in the built executable.

The failure can occur in different code paths in a suite of hundred of tests, since the error is very sporadic, we are not able to isolate it and provide a reproducible example.

But we noticed that the error always occur during a windows systemcall, in our tests we run goleak so we supposed a possible incompatibility with Go 1.26 runtime or bug in the Go runtime itself.

What did you see happen?

Here the stacktrace:

runtime: waitforsingleobject wait_failed; errno=5
fatal error: runtime: setevent failed; errno=6
fatal error: runtime.semawakeup

Thanks for the report. Can you also try this at tip (1.27 to be), and also using the new GOEXPERIMENT=goroutineleakprofile feature (see https://go.dev/doc/go1.26#goroutineleak-profiles, and proposals #74609 and #75280)?

[StefanoBalzarottiNozomi]

thanks @dmitshur, we enabled GOEXPERIMENT=goroutineleakprofile in our CI, if works well we can keep it and try to disable goleak and monitor the situation.
When we will get a new error we will report to you. Since it's very sporadic it may requires some days to get another failure.
For trying the latest Go compiler (1.27) to be, we can fetch the one in master branch and do a bunch of runs in CI, but we can't keep it until a stable version is released.
Since the failure is very sporadic, I doubt it would be useful .

[alexbrainman]

set CGO_ENABLED=1

I noticed you set CGO_ENABLED to 1. Why?

Thank you.

Alex

[StefanoBalzarottiNozomi]

We are using some C libraries in our project, so we cannot remove cgo.

[alexbrainman]

We are using some C libraries in our project, so we cannot remove cgo.

Then you should provide a reporo scenario.

It is very difficult to say what is broken in your program by just looking at the stack trace you provided. For example, C libs could corrupt runtime.

Alex

[StefanoBalzarottiNozomi]

I will do if I can find some code that can fail deterministic in n runs or with an X probability, but we never had the same failure in the same location.
What I can say is that even if we compile all unit tests with CGO, because some use C libraries, one unit test that failed, doesn't involve any C code call.
We can try to disable CGO just for tests that doesn't require CGO.

I can't share all the source code of our project, because it's closed source, but I can share the code of one very simple test that failed:

func TestResolveLongPath(t *testing.T) {
	rootDir := "C:\\"
	path := filepath.Join(rootDir, "aaaaaaaaaaaaaaaaaa")
	shortPath := filepath.Join(rootDir, "aaaaaa~1")
	f, createErr := os.Create(path)
	require.NoError(t, createErr)
	require.NoError(t, f.Close())
	defer os.Remove(path)
	assert.FileExists(t, shortPath)
	assert.FileExists(t, path)
	resolvedPath, resolveErr := ResolveLongPath(shortPath)
	assert.NoError(t, resolveErr)
	assert.Equal(t, path, resolvedPath)
}

func ResolveLongPath(path string) (string, error) {
	pathUtf16Ptr, err := windows.UTF16PtrFromString(path)
	if err != nil {
		return "", err
	}

	bufSize, longPathErr := windows.GetLongPathName(pathUtf16Ptr, nil, 0)
	if longPathErr != nil {
		return "", longPathErr
	}

	buf := make([]uint16, bufSize)

	_, getPatherr := windows.GetLongPathName(pathUtf16Ptr, &buf[0], bufSize)
	if getPatherr != nil {

	}

	return longPath, nil
