My secret sauce to debugging is formulating hypotheses about what went wrong then instrument the software to validate the hypotheses. By instrumenting I am talking about manipulating running software to give me information. Sometimes the manipulating step is made unnecessarily hard, and the trick is to force the hand. I see myself an inquisitor of software and use programmatic torture to get what I want to know. That's the central attitude to debugging. The devil is in the details, there are many possibilities to get information: using a runtime debugger, insert output statements, read the logs, use LD_PRELOAD, use strace, and so on.
