Message202789
Here's an improved repro script.
I believe it demonstrates that it is the combination of subprocess.Popen and threading that causes the problem.
Here's the output from my Windows XP VM:
***
c:\...> c:\Python33\python.exe repro_improved.py

Note that:
- even when subprocess redirects to DEVNULL there are errors
- when no subprocess.Popen is executed, no errors occur (the file is created as normal, but is not used by subprocess.Popen) |
