------- Comment #28 from michael dot olbrich at gmx dot net 2007-12-04 10:56 -------
With the latest debian packages:
g++-4.2 (GCC) 4.2.3 20071123 (prerelease) (Debian 4.2.2-4)
g++-4.3 (Debian 4.3-20071130-1) 4.3.0 20071130 (experimental) [trunk revision
130545]
Same speed for benchmark.cpp but _not_ for the original gcc-bug-report.tar.gz:
g++-4.3 is a bit faster than when I first tested (0m14.248s vs. 0m15.891s) but
nowhere near g++-4.2 (0m4.495s).
