Given all of this, it's not really a surprise that he's not clear on responsible disclosure policies (this doesn't really violate 'full disclosure policies' - he's fully disclosing it, after all!). It sounds like he was just playing around with things, found a way to crash his own machine by accident, and decided to post it online.
I also note that the code is incomplete, and looks reasonably straightforward and correct from casual inspection. I wonder if the real cause is elsewhere?
Also, the code is complete: check the tarball listed at the end of the page.
Well he kinda marked it down like he was.. talking about compiling an exe and all to crash any Vista/7 in 30 secs.
Then again; every 12 months or so the debate regarding full/responsible/no disclosure flares up again in the security-/IT-industry after another public outcry regarding one specific bug, company or patch. In the end nothing is resolved and we still continue to rely on gentleman agreements.
