If I build the demo inside the docker environment, I can run it outside the
environment and it works. I can't run it inside the environment because I get
'Could not connect to any X display' which I think is expected.

Arch
Here's if I try the demo (built with my distro stuff, not the docker env):
bbigras@bruno ~/rust-qt-binding-generator/build/demo (git)-[1a5c019...] %
./Demo
[1] 32441 segmentation fault (core dumped) ./Demo
