Combination graphviz and debug statements. If really strange things are 
happening the most likely culprit is unintended nondeterminism. Often I 
will shrink the machine (and cut back the input) to narrow down 
problems. If you bring it down to something really small and 
incrementally enable components, all the while testing your assumptions, 
you can often find the source of the problem quite quickly.
