That message means "there is a bug in your compiler".
I just installed Centos 5.3 on both 32 and 64-bit machines yesterday
to do some testing, and Sage builds no problem with the default
compiler that they include by default, which is gcc-4.1.2.
wst...@centos53-32:~$ gcc -v
Using built-in specs.

Is there any possibility that you could install 4.1.2? Sorry for all
this trouble, but until recently I think RedHat (hence CentOS) have
been just notorious for shipping modified (and broken) versions of
GCC, that have caused tons of trouble for building Sage.
By the way, I was building sage-4.1.2.rc0, and in both cases exactly
one long doctest failed with a timeout, which :
sage -t -long
"devel/sage/sage/groups/perm_gps/partn_ref/refinement_matrices.pyx"
*** *** Error: TIMED OUT! PROCESS KILLED! *** ***
*** *** Error: TIMED OUT! *** ***
A mysterious error (perhaps a memory error?) occurred, which may have
crashed doctest.
[1800.1 s]
The test that fails with a timeout is:
sage.groups.perm_gps.partn_ref.refinement_matrices.random_tests(180.0,
100, 200, 40)
