[Bug 1234578] Re: [xmir] unity-system-compositor crashed with SIGSEGV in boost::asio::detail::epoll_reactor::deregister_descriptor()

 

XMir 1.0 (the old Xorg extension) is now deprecated and is not being
maintained or fixed. It is replaced by the new 'Xmir' binary (package
'xmir') introduced in Ubuntu 15.10 wily.

Is there any way to reproduce this bug without the old Xmir?
