Overview: generating /etc/X11/xorg.conf using nvidia-xconfig 390.48 as root crashes GDM 3.28.1 at startup

Steps to Reproduce:
    1) install nvidia package on Arch Linux as root on a fresh install (/etc/X11/xorg.conf shouldn't exist)
    2) execute nvidia-xconfig as root
    3) reboot the system

Actual Results: GDM crashes and hangs the tty

Expected Results: GDM starts correctly

Build Date & Hardware: 2018-04-18 Gnome 3.28.1 Arch Linux / Lenovo Y520-15IKBN - NVIDIA GeForce 1050 Ti

Additional Information: the /etc/X11/xorg.conf file seems to be generated correctly if there is info in there already (I have made some settings to enable NVIDIA Optimus following the steps in the Arch Linux Wiki page). I have attached the crash journalctl, as well as the 2 xorg.conf files: the one that crashes GDM and the one that doesn't (before and after generation).

I can't reproduce this anymore, but the first time I got this crash I got a segfault (journal-initial). After that, I got only the second part (journal-second).
