[New-bugs-announce] [issue34233] subprocess.check_output goes to infinte loop

[sanjay patel]

New submission from sanjay patel <patel.sanjay197 at gmail.com>:

Below snipped goes to infinite loop when running through windows command prompt but works in python IDLE

import subprocess
subprocess.check_output('cmd.exe dir', stderr=subprocess.STDOUT)

save as:test.py
in windows cmd use command: python test.py
then it goes to infine loop but the same program works in Python IDLE.
