Unfortunately I can't provide the source code here since it's covered under SPEC's license. A SPEC licensee (from SuSE, RedHat and friends) should be looking at this issue. >How-To-Repeat: Compile the 176.gcc benchmark from the SPECcpu2000 benchmark suite (www.spec.org/osg/cpu2000/) with OPTIMIZE="-O3 -march=pentium4" using gcc 3.2.2 (Release), then run it the usual way ("runspec"). >Fix: Yes, please! ;) >Release-Note: >Audit-Trail: >Unformatted:
