OK - I may have 'tested' some of it already.

Other than NOT using 'portsnap', and having different CPU & RAM, specifically:

ASUS P5K, 4 GB DDR 800, Core-2 Quad 2.4 GHz,

GigaByte G33-DS3R, 4 GB DDR 800, Core-2 Quad 2.4 GHz

But we DO have overlap with the FreeBSD versions you are trying, ex:
i386 & AMD-64 Aug, Sep snapshots. cvsup from October onward 'til about 2 days ago.

- two instances of make build~ failing to complete. OK with new cvsuping 12 
hours later. Might have been OK within minutes if re-pulled. 'not known'

- a few instances of pkg_add being unable to find a consenting tarball, but a 
make install from the ports tree working OK for the same port.

- a few instances of a 'common' port refusing to build on AMD-64 at all (Opera 
comes to mind). Not to mention the odd few ports simply marked as 'broken'.

No occcurence of the sort of error you cited.

JMHO, but...

"SWAG" - most likely to be stale debris in your build environment. We either 
nuke /usr/src, or rely on the 'delete' tag to clean it up for us.

Second choice is RAM complement. Third suspect is RAM quality.

Meanwhile;

- Give me the *exact* commands you are using, I'll try them, too.

- See if you can lay hands on another 1 GB of RAM and if it at least delays the 
issue.

Standing by...

Bill
