Hello Dicek, I couldn't reproduce the segfault on my system (Arch) with RIOT-2016.10. Can you provide the core dump file? This way, we would at least know where the crash occured. If no dump file is generated, then you can also run `PORT=tap0 make debug` instead of `PORT=tap0 make term`. This command will start your binary in gdb and you can run RIOT by typing `run` in the gdb shell. In this mode, more information regarding the segfault should be displayed.
BTW, Ubuntu12.04 is pretty old (: Do you have experience with Vagrant[1]? There is a Vagrantfile in RIOT's root directory, which can be used to jump-start a RIOT VM (Ubuntu16.04) with all necessary tools pre-installed. You can find more information here [2].
