The sooner people make their peace with this, the better. Yes, with that above RelWithDebInfo change, GNU ld tends to use ~5G of memory to link the larger llvm executables, so that is definitely beyond i386, even if you run it in a jail on an amd64 host. And if you would want to use link time optimization, the requirements will increase even more... -Dimitry --Apple-Mail=_592CEB00-EFD3-48EB-AA9E-58C9F49FC2FF Content-Transfer-Encoding: 7bit Content-Disposition: attachment; filename=signature.asc Content-Type: application/pgp-signature; name=signature.asc Content-Description: Message signed with OpenPGP -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.30 iEYEARECAAYFAljdctQACgkQsF6jCi4glqOAPACg7xTJA7vHB7TjgbXTSEJIZWYZ IncAoIDyrx2mNKWkPlV8Xathqx4p1FY9 =4mOQ -----END PGP SIGNATURE----- --Apple-Mail=_592CEB00-EFD3-48EB-AA9E-58C9F49FC2FF--
