Discussion related to cado-nfs

[Paul Leyland <paul.leyland@gmail.com>]

A few days ago I had to rebuild my AMD-64 system with the latest Gentoo.
A fresh copy of cado-nfs-2.0.tar.gz was subsequently unpacked correctly.
"make" ran without complaint.  Running

./factor.sh 90377629292003121684002147101760858109247336549001090677693 -t 2

ran the poly finding and sieving stages without issue.  The filtering
stage then crashed with the full log as given below.  If desired I can
package up /tmp/cado.VgIbqQcYNM and make it available.  It is 17M
uncompressed and far too big for this email.

Strangely enough the same procedure worked perfectly on another Gentoo
amd64 system just after the initial release of CADO-NFS V2.0.

Any suggestions as to how I should proceed?

Thanks,
        Paul
