Sorry to jump in so late, but I had significant problems with
optimization for 64-bit executables under CentOS 4.x. If you can't
upgrade, I suggest dialing down the optimization flags. I had to drop
from -O3 to -O2 so that Crypto++ 5.5.2 would run, for example. At some
point I could drop support for RHEL/CentOS 4.x from my client's products
and try going back to -O3, but the required testing hasn't been real
high on the priority list.

Assuming the SVN configuration scripts can distinguish between the
releases, I suspect that changing the default optimization flags for
RHEL 4.x will be simpler than trying to fix the new UTF-8 code. Have
you tried intermediate levels of optimization? We went to production
with -O2, so it's not as if all 64-bit optimizations were broken.
