Netsniff-ng links among others against libnl-3, libnl-genl-3 and libpcap. But the current stable libpcap links against libnl-1 (the ebuild is slotted). So, upon starting netsniff-ng, it loads both version of libnl which in turn will cause a segfault because of the several abi-breaks between these versions. As soon as you unmerge libnl-1 and force libpcap to link only against libnl-3 (tested with 1.5.3 of libpcap with useflag netlink enabled) this will go away. You may want to depend on dev-libs/libnl:3 alone with slot 1.1 blocked. Foolishly I don't have the core and strace-file left on my machine. But I can reproduce these if you want. Reproducible: Always Steps to Reproduce: 1. Merge current stable libpcap with netlink-useflag enabled (it should depend on dev-libs/libnl:1.1) 2. Merge net-analyzer/netsniff-ng-0.5.8_rc3 3. Run netsniff-ng Actual Results: Segfault Expected Results: No Segfault :)

Does this still persist on net-libs/libpcap-1.6* ?
