I build GCC 4.8.0 on the exact same platform that I built GCC 4.7.3 and yet I see really quite different results. Is anyone out there seeing clean results from 4.8.0 ? thus : http://gcc.gnu.org/ml/gcc-testresults/2013-04/msg03091.html and thus http://gcc.gnu.org/ml/gcc-testresults/2013-04/msg02958.html Exact same system and nothing changed between builds. dc
