GnuTLS, without Gcrypt, without Kerberos, without PortAudio, without AirPcap.
NOTE: this build doesn't support the "matches" operator for Wireshark filter
syntax.

Running on Linux 2.6.22-14-generic, with libpcap version 0.9.7.

Built using gcc 4.1.3 20070929 (prerelease) (Ubuntu 4.1.2-16ubuntu2).

While opening a pcap file I get a coredump. I will upload the coredump to this
ticket.

The crash happens in both Linux and Windows.

A workaround that I found for the crash issue is to first chop the packets to a
smaller size, using editcap -C. This probably prevents the full data in the
packets to be read, so that the crash does not happen.

Unfortunately I cannot provide the pcap file itself because it is customer
private data.

I hope that you can look into this coredump. I can replicate this coredump
anytime. If you need any more information, I would be glad to provide it.

Thanks,
Casper
