Bug report

importsubprocesssubprocess.run('true',stdout=subprocess.STDOUT,cwd='./')

Expected output:

• Some kind of error stating that the stdout argument cannot take a subprocess.STDOUT. That subprocess.STDOUT is only valid for stderr

Actual output:

OSError: [Errno 9] Bad file descriptor: './'

I reproduce this with the latest Python main branch as well as Python 3.10 but I see no indication this issue was ever addressed
