I've submitted PR ports/165787:
  http://www.freebsd.org/cgi/query-pr.cgi?pr=165787
with a patch that temporarily comments out the
breakage.

@Carsten: I hope you can pinpoint the problem. I suspect
a change in FreeBSD's CAM layer API/ABI that causes some
sort of buffer overrun on RELENG_9. The patch points to the
exact line of code that causes dvdisaster 0.72.3 to crash.

Thanks,
