Maybe or maybe I have done something wrong on my system. FWIW, I do all my
builds with debugging enabled.

BTW, just to confirm, I was able to work around the original issue once I
updated past r235068. I had to disable DTrace build and build and install
a new libthr, then was able to re-enable DTrace and everything was fine.

Thanks,
Steve
