Package: libpython2.7-stdlib
Version: 2.7.9-2
Severity: important
File: /usr/lib/python2.7/ctypes/__init__.py
Dear Maintainer,
We're currently running our systems on the grsec kernel. However, this
breaks functionality of the ctypes module. Upon importing ctypes, this
is what happens:
Python 2.7.9 (default, Mar 1 2015, 12:57:24)
[GCC 4.9.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.

The following lines appear in the dmesg output:
