It fixes a possible crash in clang 3.4, which can occur if newer versions of llvm are compiled.

The fix was also merged to stable/9 in r286035. As far as I know, we have always required people to upgrade to the latest revision in stable branches before attempting to hop to the next stable branch (or head). -Dimitry --Apple-Mail=_CE82138D-E19C-40DD-BF2D-FA7086897965 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 v2.0.30 iEYEARECAAYFAlgDxJcACgkQsF6jCi4glqOBlgCbB9sw/whzahXYqwhg2CfvwBCB 9+8AoIgfTLI1DKCKXte9qyH2n5is8/tT =oTUE -----END PGP SIGNATURE----- --Apple-Mail=_CE82138D-E19C-40DD-BF2D-FA7086897965--
