My guess is that mozjs-52 is the culprit. My reasoning is
that only two tarballs show this problem: gjs and gnome-shell.
And those two programs are the only ones linked to mozjs.

My mozjs is the official one from firefox-52.3.0esr
I guess most distros have their own patched ones.
So my question now:
Which one is officially approved by the gnome-developpers?
