[New-bugs-announce] [issue13524] critical error with import tempfile

[Andrey Morozov]

New submission from Andrey Morozov <andrey.morozov at itseez.com>:

run_me.py: 
import subprocess, sys
e = {'PATH_TO_MY_APPS' : "path/to/my/apps"}
p = subprocess.Popen(sys.executable + " test1.py 123", env=e, shell=True, stdout=subprocess.PIPE)
print(p.stdout.readlines())
p.wait()


test1.py:
1: import sys, os
2: #import tempfile
3: print("hello : " + sys.platform + " PATH: " + os.environ['PATH_TO_MY_APPS'])

System:
Python 2.7.2 x64, Windows x64 7 Pro + SP1

Problem:
if I run python run_me.py then I see on my stdout:
['hello : win32 PATH: path/to/my/apps\r\n']

but if I uncomment line number 2 in test1.py  and run python run_me.py then I see on my stdout :

C:\tmp\python_test>python run_me.py
Traceback (most recent call last):
