Cicero is:

[wstein@cicero sage-3.1.2]$ cat /etc/issue
Fedora release 8 (Werewolf)
Kernel \r on an \m

[wstein@cicero sage-3.1.2]$ uname -a
Linux cicero 2.6.25.9-40.fc8 #1 SMP Fri Jun 27 16:25:53 EDT 2008 i686 i686 i386 GNU/Linux

The problem is gone with Sage 3.1.4 with the system compiler as well as gcc 4.3.2.
