Description of problem:
when run with -t option, tcpick will crash before first package will be displayed.
Version-Release number of selected component (if applicable):
tcpick x86_64 0.2.1-14.fc9
Steps to Reproduce:
1. tcpick -i eth0 -C -a -t
when run 'tcpick -i eth0 -C -a' everuthing is ok.
*** buffer overflow detected ***: tcpick terminated
On ix86, I can't reproduce, looks like something x86_64 specific. Is SELinux
enabled? If yes, can you please switch to permissive and see whether it crashes
as well? I think, it doesn't change anything, but just to be sure. Adding the
libpcap maintainer, Miroslav, on copy as well, maybe he has some ideas.
The crash is producible with Fedora 10 (x86_64) as well.
I have SELinux disabled as usual.
(PS. It costs too much troubles to deal with all this not working things because of SELinux contexts not set properly)
Lubomir, as spoken with you on IRC, I'm re-assigning to you. Maybe you're able
to provide a fix/patch to solve this?

[14:58:41] < lkundrak> rsc: well, to some extent
[15:00:38] < rsc> lkundrak: do you maybe have a clue how to fix #492109?
[15:02:21] < lkundrak> rsc: probably yes. I'm going to take a look at it,
feel free to reassign the ticket to me
