Copyright 1998-2010 Gerald Combs <gerald@xxxxxxxxxxxxx> and contributors.

Compiled (32-bit) with GLib 2.16.6, with libpcap 0.9.5, with libz 1.2.3,
without
POSIX capabilities, with libpcre 7.8, with SMI 0.4.8, with c-ares 1.5.3, with
Lua 5.1, with GnuTLS 2.6.2, with Gcrypt 1.4.3, with MIT Kerberos, without
GeoIP.

Running on Darwin 9.8.0 (MacOS 10.5.8), with libpcap version 0.9.5, GnuTLS

Built using gcc 4.0.1 (Apple Inc. build 5488).

--
The following command will core dump.   (It also core dumps when a capture file
is used instead of /dev/null.   This is just an easy way to demonstrate the
problem.)

tshark -V -T ps -i - < /dev/null
%!
%!PS-Adobe-2.0
%
(a bunch of PostScript)

Bus error


The error does not occur with -T text, -T psml, or -T pdml.


The problem was reproduced using the official download of 1.2.10 from
wireshark.org.   However, it also occurs in our built-from-source version 1.2.4
on darwin and linux.   The 1.2.4 backtrace is:

Program received signal SIGSEGV, Segmentation fault.
