Xwayland crashed with SIGABRT in OsAbort()

Related to https://bugs.launchpad.net/ubuntu/+source/gdm3/+bug/1773665

Whenever as root in a terminal, I start 'gvim', the whole windows system crashes and the user find himself on the gdm login screen. Windowing session has been lost.

It only occurs with gvim. I tried xterm, terminator and gthumb as root and these graphical application do not cause the crash.

Ubuntu 18.04 Bionic Beaver, all packages up to date as of 2018-05-27 11:26:45 EDT.
