You can quickly verify if this bug is present on your system when you compile the test program Maxim Sobolev posted here http://groups.google.com/groups?hl=en&lr=&ie=UTF-8&oe=utf-8&frame=right&th=848249298f77552a&seekm=7e40su4hduj42eufbh2e8vfahgutah94ch_4ax.com%40ns.sol.net#link1 Now what I want to do is, kill the bug with pcm & mmap _before_ 4.8 and I would need some pointers where I can start debugging this. --QRj9sO5tAVLaXnSD Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.1 (FreeBSD) iD8DBQE+WomNmArGtfDbn0QRAlMLAJ0dX1RwCts9FV5NJftvI29JYAc9XQCgwfj5 LB6w5o/yPt6auvZEUnvW0Sg= =LHFs -----END PGP SIGNATURE----- --QRj9sO5tAVLaXnSD-- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
