On my laptop (x86-64, Linux 3.13, 12 GB RAM): $ python3 -c "[i for i in range(999999999)]" zsh: killed python3 -c "[i for i in range(999999999)]" $ dmesg | tail -n 2 [404714.401901] Out of memory: Kill process 10752 (python3) score 687 or sacrifice child [404714.401903] Killed process 10752 (python3) total-vm:17061508kB, anon-rss:10559004kB, file-rss:52kB And your test.py produces the same result. Are you sure you don't have a ulimit set on address space?
