FYI, I have rebuilt the F-9 RPM with optimization turned off and 
submitted it for an update (should hit the mirrors sometime soon).

Just a heads up. I have some time constraints at my end. The only thing 
I had time for before leaving until next Wednesday was to rebuild the 
package, I cannot not confirm at this moment if the resulting package 
resolves the issue, but given the comments in this thread it would 
appear to solve the problem in the near term. I thought it was 
worthwhile to push the new RPM out, even under these constraints.

When I return I will investigate the root cause of the failure further. 
Obviously this is a temporary workaround and if there are compiler 
issues it needs to get addressed as soon as possible.

In the interim I would appreciate feedback on the new package.

The new package is: freeradius-2.0.3-3.fc9

My sincere thank you to everyone who contributed to diagnosing the 
problem and my apologies for not catching this earlier.
