--- 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 create
new VMs. I've isolated the LLVM revision that broke it, but I'm still working
out which of the two scenarios is the actual problem.
