I am using some very old installation of Zope server with its own archaic Python. Under new kernel (3.13.0-59-generic #98~precise1-Ubuntu SMP Fri Jul 24 21:05:34 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux) any call of os.system in this Python fails with error code 139 (SIGSEV), under previous kernels (until 3.13.0-58) it worked OK:
$ /opt/zope/bin/python
Python 2.1.3 (#1, Sep 19 2002, 13:15:46)
[GCC egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)] on linux2
Type "copyright", "credits" or "license" for more information.
>>> import os
>>> os.system('pwd')
139
>>>
Obviously I am not sure whether the source of the problem is kernel or not, all I know then after rebooting with older kernel my application works all right, when rebooting with 3.13.0-59 it crashes on those failed os.system calls.
I am using Ubuntu 12.04, 64-bit.
