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.

By SPEC rules, you're allowed to pass -fstrict-aliasing to vortex.
