Hm. In my experience, if you attempt to debug the VM at the level Alexander intended, you usually do not get very far without rebuilding, if only to get a fastdebug or slowdebug build. And if you have the knowledge to debug the VM, building it should be not a big hurdle.
Just my 5c.. (Should you attempt to rebuild on Windows, there are a number of how-tos floating around.
