New submission from Alexander Haensch:

I recieve a segmentation fault if i call os.forkpty(). It does not happen with 
os.openpty(). Moreover os.fork() works fine.

The basesystem is gentoo-hardened. It does only happens if threading is 
enabled, which is the standard.

Tested python versions: 2.7.10, 3.4.3 
Some backtraces and py-bt are found here:

https://bugs.gentoo.org/show_bug.cgi?id=584916

Is this a known issue? At the moment i am thinking that gcc is "optimizing" 
something here.
