Which line generates the error and how do you know which variable on that line is the culprit? I'm sure you know that the line number can be misleading due to if statements and such.

Can you reproduce the problem in a smaller sample program?

Is it consistent? (That is, it always faults for the same input data.)

Does it fault if you comment out the "irrelevant" stuff?
