I can confirm that on a FreeBSD 7-STABLE AMD64 server running vtun-3.0.2 and lzo2-2.03_1 installed from ports, use of lzo:9 compression causes vtund (running in server tunnel mode) to segfault the moment I attempt to send any data over the tun device it instantiates. Switching to using zlib compression completely resolves the issue. I've examined the core file it dumps in gdb and unfortunately it's completely useless. I'll try have a go at truss'ing or ktracing the vtund process and report back if that produces anything useful.
