I reran test with IDLE started 4 ways:
I am closing this as out of date because the problem seems to have been fixed elsewise.

3.8.0a2+ 32 bit debug python, built today, opened from python icon, then idle started with 'import idlelib.idle'
3.8.0a2 64 bit installed, directly from IDLE icon
3.7.2 python -m idlelib
3.7.2 pythonw -m idlelib

#  and it ran correctly all 4 times.
>>> import subprocess
>>> p = subprocess.Popen(["python", "-c", "print(32)"], stdin=None,
stdout=subprocess.PIPE, stderr=subprocess.PIPE)
>>> p.communicate()
(b'32\r\n', b'')

Anyone with the same or similar failure on current Python (now 3.7, 3.8) should open a new issue and give careful details -- release or build, system, startup procedure, and a reproducing example only using stdlib modules (no PythonWin).
