It shouldn't be trying to print Packet-Src-IP-Address as it isn't a real attribute.

Could you provide the contents of the request, I can't get it to crash on my system, and the backtrace provides no clue about which attribute it's failing at printing.

OK, what compiler/OS are you using. It means that the preprocessor macros in ./build.h couldn't figure out the endianess of the system, which is odd as the Macros should cover at least GCC and clang.
