You would need to provide a lot more information before I could venture a suggestion. But I don't think it would be useful for you to provide all that information. The gcc-help mailing list works best when you ask a specific question. I would encourage you to use your own debugging skills first to narrow down what is happening to the point which you find hard to understand. Ian
