Hmm... funky. I can reproduce the issue on a newer Intel machine:
$ cat /proc/cpuinfo
processor : 0
vendor_id : GenuineIntel
cpu family : 6
model : 23
model name : Intel(R) Xeon(R) CPU L5410 @ 2.33GHz
stepping : 6
cpu MHz : 2327.445
cache size : 6144 KB
physical id : 0
siblings : 4
core id : 0
cpu cores : 4
....
$ time ./test41
real 0m6.270s
user 0m6.268s
sys 0m0.000s
$ time ./test44
real 0m5.524s
user 0m5.523s
sys 0m0.000s
$ time ./test46
real 0m11.721s
user 0m11.718s
sys 0m0.001s
P.S. the middle one is made using g++ (GCC) 4.4.5 20110214 (Red Hat
4.4.5-6). The rest are original binaries made a couple of days ago.
