tcpxtract

This programme causes segmentation faults when processing wireless derived
data streams. Specifically:

Ubuntu 6.1 running on an i686 system.

Data is derived from monitoring wireless links using Kismet. The Kismet
dump file is processed to remove 802.11 headers using airdecap-ng and then
fed to tcpxtract.

The crash occurs in the set_segment_marks function in extract.c, I have not
yet been able to determine the mechanism that triggers this, however the
seg fault occurs when the eptr->segment.start = 0; line is executed - I
assume this is because the address of eptr->segment.start is somehow
invalid.
