[Pytest-commit] Issue #260: Fatal Python error when running 32bit Python via tox on Windows (hpk42/tox)

New issue 260: Fatal Python error when running 32bit Python via tox on Windows
https://bitbucket.org/hpk42/tox/issue/260/fatal-python-error-when-running-32bit

Florian Bruhin:

With this tox.ini:

```ini
[testenv]
commands = {envpython} -c 'print("Hello World")'
basepython = C:\Python34_x32\python.exe
```

and a minimal setup.py:

```python
from setuptools import setup
setup()
```

I get this when running it on Windows:

```

Fatal Python error: Failed to initialize Windows random API (CryptoGen)
Running virtualenv with interpreter C:\Python34_x32\python.exe

```

Searching for the error [it seems](http://bugs.python.org/issue20614) this happens when `SYSTEMROOT` is not set.

Even though `SYSTEMROOT` is printed in the environment above, I tried to add `passenv = *` and `setenv = SYSTEMROOT=C:\Windows` without any success.

When I run that Python install by hand, it works fine. When I use a 64bit install instead of the 32bit one on the same machine, it's fine as well.

I also tried downgrading to 1.9.2 and it happens there as well, so it doesn't seem to be a recent `passenv` change.
