Dear GHC team, I have tested ghc-6.10.2.20090430 under Debian Linux, processor = (GenuineIntel cpu family 6, Intel(R) Core(TM)2 CPU 6400). It looks all right. The test was: 1) making ghc-6.10.2.20090430 from source by ghc-6.10.2, 2) making DoCon and running its test, 3) making Dumatel-1.06-pre and running its test, also with -enable-library-profiling and a bit of time profiling (for any future occasion: profiling is important).
