Hi Russ,

Minus --prefix and some of the --with-* overrides (because I am building
this as an unprivileged user and have compiled the needed libraries in
my home folder), this is my configure line:

./configure --enable-ipv6 --enable-zlib --enable-gre --enable-mpls
--enable-decoder-preprocessor-rules --enable-pthread --enable-debug-msgs
--enable-debug --enable-react --enable-flexresp3 --enable-normalizer

My command line is this:

snort -c local.rules -k none -A console --pcap-dir <dir>/ -q

On a whim, I just tested using -r <pcap>, and that does not trigger the
SIGSEGV.  It does happen if you use --pcap-dir and have the referenced
PCAP file in the target directory PLUS this SCTP sample from WireShark's
Sample Captures:

Also, using --enable-sourcefire causes this SIGSEGV to disappear.  What
is that configure flag doing, exactly?
