http://people.redhat.com/dnovillo/spec2000/ shows that gcc 4.1 has been failing vortex in SPEC CPU 2000 on Linux/EM64T and Linux/PPC64 at least since Aug. 7, 2005. The current gcc 4.1 also failed vortex on Linux/ia64. Is that a known issue?
Yes this is an aliasing violation inside of the sources of vortex see PR 23449. Note 127.gcc has similar issues too but I don't know why nobody have brought this up to SPEC. I was trying to get Apple to do it a couple of years ago and then trying to get SUSE to do it but I could never get anyone with enough courage to propose my fix of using memset instead of casting.
