It's also on a relatively ancient distribution and GCC version. You could try reportig the bug to Red Hat to see if they are willing to provide a fix. Failing that, probably the best thing to do is just to use configure --disable-tls on a RHEL4/ia64 system. The main purpose of the use of thread local storage is to avoid duplicate UUID's on SMP systems when you have multiple threads generating UUID's at a very high rate. Certain database-driven applications will have a problem here, but it's not clear it will matter for most users of Lustre.
