Why debugging is so difficult?
Some characteristics of bugs provide some clues:
1. The
symptom and the cause may be geographically remote. That is, the
symptom may appear in one part of a program, while the cause may
actually be located at a site that is far removed. Highly coupled
program structures exacerbate this situation.
2. The symptom may disappear(temporarily) when another error is corrected.
3. The symptom may actually be caused by no errors (e.g. round-off inaccuracies).
4. The symptom may be caused by human error that is not easily traced.
5. The symptom may be a result of timing problems, rather than processing problems.
6. It
may be difficult to accurately reproduce input conditions(e.g. a
real-time application in which input ordering is indeterminate).
7. The symptom may be due to causes that are distributed across a number of tasks running on different processors.
