Hi, sorry, been pretty busy, and will be for a few days, so my replies may not be instant!

Having looked through the dis test module, to be honest, I can't even find a call to dis.findlabels...odd. Maybe I've got it wrong, and I wouldn't mind somebody else taking a look! But either way, a quick overview shows me that it basically picks up functions, figures out the disassembled function, and compares expected output, in a similar way that we're working, actually. 

I'll look through your example, which looks pretty good! It works as expected on my repo (fails and passes appropriately), and I'll see about improving it, but for now, it seems to do its job.
