There were some postings recently, about newer versions of FreeBSD being supposedly more "swappy", see e.g.: = http://lists.freebsd.org/pipermail/freebsd-stable/2014-April/thread.html#7= 8361 I have no idea if this is really substantiated with evidence, or just a feeling, though. :) In any case, when you are experiencing mysterious compiler errors, and your system is heavily exercising RAM and swap, it is always a good idea to do a full hardware diagnostics test. For your RAM, you can use memtest86+, and since you have a Dell, you can use their diagnostics program to test other parts of the machine. -Dimitry --Apple-Mail=_1A19FFD7-A2BB-4B9D-ABF5-D5A4B71C8240 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 v2.0.22 (Darwin) iEYEARECAAYFAlNUFJMACgkQsF6jCi4glqNQpACgkVjxlzG96DjJ737QHcC7J+h4 Br0AniP4XjnfTvOG7MqCpKQSGMSIwCoZ =Mw3X -----END PGP SIGNATURE----- --Apple-Mail=_1A19FFD7-A2BB-4B9D-ABF5-D5A4B71C8240--
