--- Comment #20 from Kyle Evans <kevans@freebsd.org> ---
(In reply to Jason W. Bacon from comment #19)

LLVM 8 and higher miscompile it due to either a bug in their tail-call
optimization or VirtualBox doing something funky, and one can no longer cre=
ate
new VMs. I've isolated the LLVM revision that broke it, but I'm still worki=
ng
out which of the two scenarios is the actual problem.
