Comment 1 Robert Scheck 2009-03-25 09:04:55 EDT
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.
Comment 2 JanS 2009-03-25 09:26:56 EDT
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)
Comment 3 Robert Scheck 2009-03-29 09:05:21 EDT
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?

[14:53:42] < rsc> lkundrak: aren't you C knowledged?
[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
