My guess would be a fault in wireshark. Try it with some other UDP
software and see if it has the same error. Manually compute the UDP
checksum and see if it matches.

Hard to say anything about this without seeing the actual code in
question. It would also be handy to see the exact stack trace that gdb
produces.

What's the exact error, and how do you set it from 9 to 16? What
crashed, what was your code, what was the stack trace of the crash?
Basically, we need a whole lot more information before we can say too
much about any of this....
