runtime error: invalid memory address or nil pointer dereference

[oliverpool]

For some reasons, I need to run go t.Run. However this triggers a runtime error: invalid memory address or nil pointer dereference:

package mypackage

import (
	"sync"
	"testing"
)

func TestParallel(t *testing.T) {
	wg := &sync.WaitGroup{}

	wg.Add(1)
	go t.Run("subtest", func(t *testing.T) {
		defer wg.Done()
	})
	wg.Wait()
}

(I test several things that must run in parallel, running t.Parallel my block some of my substests if I have more than GOXMAXPROCS)
