The sanitizer libraries are part of compiler-rt, and the version which is compatible with clang 3.4 does not yet have full FreeBSD support. I don't think it is feasible to backport newer versions of these to accommodate an older clang version. > Wondering if we could try and add just the clang-rt libraries since = the end of 2016 is a long time away :) No, that is not easily done. -Dimitry --Apple-Mail=_5D9EF86C-B56E-44B7-B7B2-1006C2D287D6 Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP using GPGMail -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.27 iEYEARECAAYFAlUgZc4ACgkQsF6jCi4glqM6qwCgvwvoQSqGH/3FRErEb9WpTyzq V3wAoMC/TAGsfE9go6EA/U60VEM1cOKP =O4lK -----END PGP SIGNATURE----- --Apple-Mail=_5D9EF86C-B56E-44B7-B7B2-1006C2D287D6--
