Since /usr/bin/ceph-dencoder was only thing in ceph-common that links again libtcmalloc, if we could fix the over-linking there, then we avoid the whole issue. The downstream BZ that corresponds to that ceph.com Redmine ticket is https://bugzilla.redhat.com/1186953 in case anyone's interested. - Ken
