Debug test using code lens fails when `-race` is enabled

[elszon]

After upgrading go to 1.26.0 the tests run from the code lens and from the test explorer fail when -race is enabled in the test flag configuration.

VSCode config:

    "go.testFlags": [
        "-race"
    ],

test example:

package check

import "testing"

func TestCheck(t *testing.T) {
	t.Log("This is a simple test to check the testing setup.")
}

tools version:
go: 1.26.0
dlv: 1.26.0 (rebuild by new compiler)
gopls: 0.21.0

VS Code: 1.109.3
golang.go: 0.52.2

Hi @elszon thank you for reporting this. Can you share the output you see when the test fails - what kind of error do you see?

[elszon]

Debugging stops on the func (p *Pointer[T]) Store(value *T) in $HOME/go/src/internal/runtime/atomic/types.go:545. On continuing debugging, the SIGSEGV is reported.

I have a similar issue.

It seems the race detector is not working in combination with the debugger.

Not sure if that warrants an extra issue.

@hu3bi Thanks, that issue does appear to be related, and there is a pending fix for it
