This issue shows on my test machine running 12-CURRENT. During linking phase of ports using boost libs I get this errors: /usr/local/lib/libboost_log_setup.so: undefined reference to `_ZTIDs' /usr/local/lib/libboost_log_setup.so: undefined reference to `_ZTIDi' Building these ports on 10 and 11 in poudriere is just fine.
See bug 214864 comment 100. This is LLD_BOOTSTRAP regression.
Confirmed. Linking is fixed on system rebuilt with WITHOUT_LLD_BOOTSTRAP.
Shouldn't happen after base r328305. http://beefy12.nyi.freebsd.org/data/head-amd64-default/p459899_s328383/logs/leatherman-1.3.0_4.log
