capture triggering the crash

Build Information:

Hi,

Here is a PCAP file triggering a crash that could enable a remote party to
trigger (a least) a remote denial of service.

This was successfully tested on 1.8.1.

This file was generated thanks to a fuzz testing campaign.

Laurent Butti.

Program received signal SIGSEGV, Segmentation fault.
