Hmm. Compiler bug maybe? I can't recall if gcc 2.96 had a good
reputation or not. You might try backing off the optimization level
and see if the behavior changes. Also see if there are any errata
available for that compiler package.
Also, is this just one machine or several? If only one, I'd try
reindexing that index and see if that helps.
