There's a reproducible segfault in 4.02 only for gettext https://github.com/ocaml/opam-bulk-logs/blob/master/20140829/roo/4.02.0/raw/gettext#L2351 Anyone got time to triage this? I'm out for a few hours so cant immediately. Looks like gettext may be double linking unix.cma, which can't be healthy. -anil
