I've downloaded: ftp://gcc.gnu.org/pub/gcc/snapshots/4.8-20120923/gcc-4.8-20120923.tar.bz2 and configured with --enable-checking=release. As a result, the gcc times to improve a lot; however, there's still the degredation of the time w.r.t. clang and the macro, LAST_LESS approaches TUPLE_SIZE: LAST_LESS gcc/clang times --------- --------------- 4 0.28 16 1.15 20 1.70 Certainly 1.70 is much better than 3.34. A new .zip file is attached. I don't know if this indicates there's still a problem. -regards, Larry
