Virtualbox crashes when X-Server is started: VERR_IEM_INSTR_NOT_IMPLEMENTED

[Marko15576]

Hello,

the host system is macOS 10.12.4, the guest a freshly installed FreeBSD 11-p9 with the newest x11 packages from the ports tree. If I try to start xfce4, virtualbox crashes (log attached). Guest additions 5.1.22 are installed. However, the crash occurs with and without installed guest additions.

It would be nice if someone could investigate that issue.

Kind regards, Marko
