Did you write this code yourself? We can't possibly help debug without at least seeing a code snippet. Is this segfault coming from a ROS node that you didn't write? Which one, and how can we reproduce the issue?

I suggest editing your question to provide more detailed information. If you are looking for a general lesson on how to debug segfaults in code you've written, then this is probably not the right place to be asking that question.

I just closed this question because as it stands, we can't possibly help you. If you edit the question, I'll re-open it. Alternatively, you can just ask a new (hopefully more clearly written) question. Thanks!

You say you are using OpenCV, but you tagged PCL... which is it? I'd suggest using print statements and/or gdb to at least narrow down where your segfault is coming from.

If your code is really that long and there is some reason you can't include it in a question (I didn't think there were limits on that?) you can try including it in a pastebin or a gist. If your code is that long, people aren't as likely to help you because it will take significant time.
