--- Comment #1 from Niels de Vos <ndevos at redhat.com> ---
Thanks Chris. I can reproduce the crashes on Fedora 27 with the steps you
provided.

  # dnf install rust cargo glusterfs-server

It does not consistently crash for me, but surely 1 out of 30 times. The stack
traces look a little different though, this one is the most common that I
encountered after running the reproducer a couple of times.

I'm not sure when I have time to look into this further, maybe Poornima gets to
is before me?
