I care about SPEC and IA-64. I will try looking at this. I am very busy though, so it may take a while. It would be reasonable to submit a bug report for this so that it doesn't get forgotten.

At the moment, I don't have SPEC2000 set up on my IA-64 machine, so I am starting from scratch here.

All of the benchmarks are compiled under "-O2".

You can find example config files on the www.spec.org site. There don't appear to be any special options for 173.applu needed on ia64-linux.

If you have time, you could try playing with optimization options. Try just "-O" to see if it works. If that doesn't work, try "-O0". If "-O1" works, then you can try adding -f options to try to isolate which one is causing the problem.

You could also try other compilers, 3.3, mainline (aka 3.5) to see if maybe it is a gcc-3.4 bug. -- Jim Wilson, GNU Tools Support, http://www.SpecifixInc.com
