Somebody else reported the same to me yesterday. This is an upstream bug with AVX (which is still present in llvm trunk), so for now you need to set your CPUTYPE to something that doesn't have AVX, or simply unset your CPUTYPE. The bug has been reported upstream, and once there is a fix, I will import it ASAP. -Dimitry --Apple-Mail=_5074E756-38D6-4181-ADDC-44E59B6EDB4E 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 v2.0.28 iEYEARECAAYFAlYVAMwACgkQsF6jCi4glqOhEQCg5j2Ga7a8m6dBlakg7v4n45ov 4gEAn3OjGpKbR8aW5RkT87HMHq7ASaCH =yR9L -----END PGP SIGNATURE----- --Apple-Mail=_5074E756-38D6-4181-ADDC-44E59B6EDB4E--
