Some poking around reveals that this is a known regression with pari
and gcc 4.1.0. See:

Well, could you just for fun rebuild pari? I think the compiler should
blow up in that case, too, and I am curious why pari's build system
doesn't catch it.
Regarding a solution: I have discussed this with William before but I
plan to offer a complete optional tool chain for compiling Sage that
is integrated into the make system just for cases like this where the
system's compiler screws us. The optional gcc spkg should work for you
for now provided you fix $LD_LIBRARY_PATH in the way I mentioned
earlier. If you do so first install the gcc spkg and then force a
rebuild of pretty much every spkg with the exception of prereq I
believe. The gcc compilers ends up in $SAGE_LOCAL, so there is no
chance it could screw up your system or have side effects on other
components.
Cheers,
Michael
