What did you do?
Go 1.13 regression: go test -race fails if test calls flag.Parse() and additional test-flags are provided
Steps to reproduce:
mkdir 113_regression && cd 113_regression
cat > repro_test.go <<EOF
package main
import "flag"
import "testing"
func init() { flag.Parse() }
func TestHello(t *testing.T) {}
EOFOn Go 1.12
go get golang.org/dl/go1.12.9 && go1.12.9 download
go1.12.9 test -race -test.parallel 8
# PASS
# ok _/go/113_regression 1.009s
On Go 1.13, running the test fails
go get golang.org/dl/go1.13 && go1.13 download
go1.13 test -race -test.parallel 8
# flag provided but not defined: -test.parallel
# Usage of /tmp/go-build008991056/b001/113_regression.test:
# exit status 2
# FAIL _/go/113_regression 0.008s
The problem looks related to calling flag.Parse(). Trying an example on Go 1.13 on a test without flag.Parse()
cat > repro_test.go <<EOF
package main
import "testing"
