Created attachment 384052 [details, diff] protobuf.patch protobuf tries to use RTTI, but if the binary it's loaded to doesn't support it, it crashes (e.g. bug #503084) Please see attached patch that fixes it. Also see https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=192821
This is fixed now with dev-libs/protobuf-2.5.0-r1 .
