One app that I care about runs slower on gcc-3.4.1 than on gcc-2.95.3. I'm putting together a performance regression benchmark suite right now by pulling together all the known microbenchmarks that run slower on newer versions of gcc, in hopes of helping make sure that gcc-4.1 resolves most of them. - Dan -- Trying to get a job as a c++ developer?
