Wow, that's an ugly bug! Thank you for reporting it. I've opened the following ticket for it: http://tcpreplay.synfin.net/trac/ticket/170 Right now I have it assigned to 3.1, but this is probably serious enough to warrant a bug fix release (3.0.1). If you're interested in testing a patch against 3.0 let me know.
