[issue24493] subprocess with env=os.environ fails with "fatal python error" when calling 32-bit python from 64-bit one on Windows

eryksun added the comment:

I can't reproduce this in Windows 7 or 10 using Python 3.4. What gets printed for the following?

import os
import subprocess

cmd32 = os.path.join(os.environ['SYSTEMROOT'], 'SysWOW64', 'cmd.exe')
subprocess.call('{} /c set SYSTEMROOT'.format(cmd32), env=os.environ)
