When I try to launch a tcpliveplay on x86_64 systems it always crashes:

[root@rhel6 ~]# tcpliveplay eth2 /root/test.pcap 192.168.1.4 12:34:01:87:92:F4 random
new source port:: 63170
Random Local SEQ: 1438605248
Segmentation fault (core dumped)

I've tried this on Fedora 20 (libpcap-1.5.3), RHEL6 (libpcap-1.0.0) and RHEL5 (libpcap-0.9.4). And I've also compiled tcpliveplay with the latest libpcap-1.6.2. Crash occurres here:

(gdb) p sched[i].tcphdr
$9 = (tcp_hdr *) 0x601000015
(gdb) p *sched[i].tcphdr
Cannot access memory at address 0x601000015

i386-i686 version works fine.

Found issue with copying raw pcap files instead of using libpcap APIs. This should also fix issues with using pcapng files, provided that installed libpcap file is up-to-date.
