If you are thinking of the assert-enabled Cog that Eliot describes here:

http://lists.squeakfoundation.org/pipermail/squeak-dev/2012-December/166750.html 
 
You can probably just use the one that Eliot provided.

I expect that this is just a matter of setting a couple of flags in the
configuration step of building Cog, so you (we) can probably do this
easily on the squeakci.org server to make your own debugging VM. We'll
need to confirm which flags to set of course.

I'm not sure how useful this would be, but it can't hurt to try it.

Next April 1, I think I'll release my SUnit enhancements to provide
support for "self shouldnt: #crash" in unit tests ;-)
