In working through the tutorial for ns3 (see http://www.nsnam.org/docs/release/3.14/tutorial/singlehtml/index.html ) I've created two simple pcap files. When I try to look at them using wireshark, I get a signal 11 (segmentation fault). I've done a backtrace and the last function call is tvb_get_guint8 from tvbuff.c. Apparently, fast_ensure_contiguous() returns NULL, which then gets dereferenced. The particularly strage part is that if I use the installed wireshark (that is, the one I just built and installed at /usr/local/bin/wireshark) I get this fault, but if I run it from the build directory, it works just fine. I've configured with --enable-setcap-install and I"m running on Fedora 19 if that matters.
I'm using the very latest trunk build:
