Stop feeding 32 bit libraries and it won't try to load them. It is as simple as that. For complex scenarious we do provide LD_32_ family of environment variables and if you refuse using them and insist on sticking with clearly broken configuration, it your problem, not rtld's. --=20 Alexander Kabaev --Sig_/Z+.yhe2Ce2Xi21EF9z+UlZD Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (FreeBSD) iD8DBQFJA2uyQ6z1jMm+XZYRAik6AJ9w8pbI1Y4uSXD8ujbzRlEQWvRhhwCg1qmk xwQnSb9dFlrSBiroH4pgF0Q= =OZK3 -----END PGP SIGNATURE----- --Sig_/Z+.yhe2Ce2Xi21EF9z+UlZD--
